At present TPL uses the same options as SPL support. In a few cases the board
config enables or disables the SPL options depending on whether
CONFIG_TPL_BUILD is defined.
With the move to Kconfig, options are determined for the whole build and
(without a hack like an #undef in a header file) cannot be controlled in this
way.
Create new TPL options for these and update users. This will allow Kconfig
conversion to proceed for these boards.

On all TI platforms the ROM defines a "downloaded image" area at or near
the start of SRAM which is followed by a reserved area. As it is at
best bad form and at worst possibly harmful in corner cases to write in
this reserved area, we stop doing that by adding in the define
NON_SECURE_SRAM_IMG_END to say where the end of the downloaded image
area is and make SRAM_SCRATCH_SPACE_ADDR be one kilobyte before this.
At current we define the end of scratch space at 0x228 bytes past the
start of scratch space this this gives us a lot of room to grow. As
these scratch uses are non-optional today, all targets are modified to
respect this boundary.

On the raspberry pi, you can disable the serial port to gain dynamic frequency
scaling which can get handy at times.
However, in such a configuration the serial controller gets its rx queue filled
up with zero bytes which then happily get transmitted on to whoever calls
getc() today.
This patch adds detection logic for that case by checking whether the RX pin is
mapped to GPIO15 and disables the mini uart if it is not mapped properly.
That way we can leave the driver enabled in the tree and can determine during
runtime whether serial is usable or not, having a single binary that allows for
uart and non-uart operation.

This commit moved the SPL stack into SRAM C, which worked when the SPL
set the AHB1 clock down to 100 MHz to cope with the flaky SRAM C access
from the CPU.
However booting with boot0 (and thus not using SPL at all) we still run
with a 200 MHz AHB1, so any access to SRAM C is prone to fail.
Since this commit does _not_ only affect the SPL code, but also the
U-Boot proper, we fail when booting with boot0.
As the introduction of tiny-printf reduced the size of the SPL, we
can afford to have the SPL stack in SRAM A1.
This reverts commit 1a83fb4a17

This series moves the CONFIG_SYS_CACHELINE_SIZE. First, in nearly all
cases we are mirroring the values used by the Linux Kernel here. Also,
so long as (and in this case, it is true) we implement flushes in hunks
that are no larger than the smallest implementation (and given that we
mirror the Linux Kernel, again we are fine) it is OK to align higher.
The biggest changes here are that we always use 64 bytes for CPU_V7 even
if for example the underlying core is only 32 bytes (this mirrors
Linux). Second, we say ARM64 uses 64 bytes not 128 (as found in the
Linux Kernel) as we do not need multi-platform support (to this degree)
and only the Cavium ThunderX 88xx series has a use for such large
alignment.

Trimslice currently stores its environment at 512KiB into the SPI flash
chip. The U-Boot binary has grown such that the size of the boot image
(which includes the Tegra BCT, padding, and the U-Boot binary) is slightly
larger than 512K now. Consequently, writing the boot image to flash
corrupts the saved environment, and equally, writing to or erasing the
environment will corrupt the bootloader, which in turn will cause the
Tegra boot ROM to enter recovery mode during boot, making it look as if
the system is non-operational. Note that tegra-uboot-flasher writes to
the environment during the flashing process.
Solve this by moving the environment as high as possible in flash. This
will allow the U-Boot binary to roughly double in size before this problem
is hit again, at which point there's nothing we can do anyway since the
binary won't fit into flash.
99% of other Tegra boards store the environment in eMMC and use a negative
value for CONFIG_ENV_OFFSET, which already automatically places the
environment as near the end of boot flash as possible. The 1 remaining
board hard-codes CONFIG_ENV_OFFSET to 2MiB, which allows for plenty more
bloat.

The meaning of CONFIG_USB in U-Boot is different from that in Linux.
As you see in drivers/usb/Kconfig of Linux, CONFIG_USB enables the
USB host controller support, while CONFIG_USB_SUPPORT is used to
enable the whole of the USB sub-system.
When I added CONFIG_USB into Kconfig by commit 6e7e9294d3 ("usb:
add basic USB configs in Kconfig"), I planned to follow the Linux's
convention, i.e. CONFIG_USB to enable/disable the USB host support.
Then, commit 68f7c5db2d ("usb: Generic USB Kconfig option, that
fits both host and gadget and comments") changed the logic of the
CONFIG_USB to point to the whole of the USB sub-system. As a result,
currently we do not have an option for USB host.
This commit adds CONFIG_USB_HOST, which will be useful to compile
in the USB host support code.
CONFIG_USB_HOST is not referenced at all, but strangely some boards
define it in board headers. I removed them because USB_HOST will be
selected in Kconfig going forward.

We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so
that it is always available to the build system. Otherwise we can run
into cases where we have inconsistent sizes of certain attributes.
Ravi Babu reported offset mismatch of struct dwc3 across files since
commit 95ebc253e6 ("types.h: move and redefine resource_size_t").
Since the commit, resource_addr_t points to phys_addr_t, whose size
is dependent on CONFIG_PHYS_64BIT for ARM architecture.
I tried my best to use "select" where possible (for example, ARMv8
architecture) because I think this kind of option is generally user-
unconfigurable. However, I see some of PowerPC boards have 36BIT
defconfigs as well as 32BIT ones. I moved CONFIG_PHYS_64BIT to the
defconfigs for such boards.
CONFIG_36BIT is no longer referenced, so all of the defines were
removed from CONFIG_SYS_EXTRA_OPTIONS.

In non-secure boot scenario from NAND, this address will map to CPC
configured as SRAM. But in case of secure boot, this default address
always maps to IBR (Internal Boot ROM).
The IBR code requires that the bootloader(U-boot) must lie in 0 to 3.5G
address space i.e. 0x0 - 0xDFFFFFFF.
For secure boot target from NAND, the text base for SPL is kept same as
non-secure boot target i.e. 0xFFFx_xxxx but the SPL U-boot binary will
be copied to CPC configured as SRAM with address in 0-3.5G(0xBFFC_0000)
As a the virtual and physical address of CPC would be different. The
virtual address 0xFFFx_xxxx needs to be mapped to physical address
0xBFFx_xxxx.
Create a new PBI file to configure CPC as SRAM with address 0xBFFC0000

------------------------------>8---------------------------
>From that layout we may calculate amount of space reserved for
u-boot.img. It's just 315kb (322560 bytes).
Now if I build U-Boot with Sourcery CodeBench ARM 2014.05 produced
u-boot.img is already more than we expected
(323840 bytes instead of "< 322560"):
------------------------------>8---------------------------
ls -la u-boot.img
-rw-rw-r-- 1 user user 323840 Jul 5 07:38 u-boot.img
------------------------------>8---------------------------
Funny enough if I rebuild U-Boot with ARM toolchain available in
my Fedora 23 distro u-boot.img becomes a little bit smaller:
------------------------------>8---------------------------
ls -la u-boot.img
-rw-rw-r-- 1 user user 322216 Jul 5 07:39 u-boot.img
------------------------------>8---------------------------
What's worse this problem might not affect people most of the time
because what happens people would just copy u-boot.img on SD-card and
live in happiness with it... well until somebody attempts to save
environment in U-Boot with "saveenv" command which will simply
overwrite the very end of u-boot.img.
That will lead to unusable SD-card until user dd u-boot.img on
SD-card again.
I may foresee this issue in the future to become more visible once we
add more features in U-Boot for Wandboard or just existing code base
becomes bulkier and people will consistently get larger u-boot.img
files produced.
IMHO there's an obvious solution for all that - just move U-Boot's env
to the very end of the gap between U-Boot and the first real partition
on the SD-card. This patch will follow
8fb9eea565 ("mx6sabre_common: Fix U-Boot corruption after 'saveenv'").
So env is still not in the very end of the gap (obviously 256kb is way
too much for U-Boot's env) but at least we have now the same
partitioning for i.MX6 boards.

Allwinner devices support SPI flash as one of the possible
bootable media type. The SPI flash chip needs to be connected
to SPI0 pins (port C) to make this work. More information is
available at:
https://linux-sunxi.org/Bootable_SPI_flash
This patch adds the initial support for booting from SPI flash.
The existing SPI frameworks are not used in order to reduce the
SPL code size. Right now the SPL size grows by ~370 bytes when
CONFIG_SPL_SPI_SUNXI option is enabled.
While there are no popular Allwinner devices with SPI flash at
the moment, testing can be done using a SPI flash module (it
can be bought for ~2$ on ebay) and jumper wires with the boards,
which expose relevant pins on the expansion header. The SPI flash
chips themselves are very cheap (some prices are even listed as
low as 4 cents) and should not cost much if somebody decides to
design a development board with an SPI flash chip soldered on
the PCB.
Another nice feature of the SPI flash is that it can be safely
accessed in a device-independent way (since we know that the
boot ROM is already probing these pins during the boot time).
And if, for example, Olimex boards opted to use SPI flash instead
of EEPROM, then they would have been able to have U-Boot installed
in the SPI flash now and boot the rest of the system from the SATA
hard drive. Hopefully we may see new interesting Allwinner based
development boards in the future, now that the software support
for the SPI flash is in a better shape :-)
Testing can be done by enabling the CONFIG_SPL_SPI_SUNXI option
in a board defconfig, then building U-Boot and finally flashing
the resulting u-boot-sunxi-with-spl.bin binary over USB OTG with
a help of the sunxi-fel tool:
sunxi-fel spiflash-write 0 u-boot-sunxi-with-spl.bin
The device needs to be switched into FEL (USB recovery) mode first.
The most suitable boards for testing are Orange Pi PC and Pine64.
Because these boards are cheap, have no built-in NAND/eMMC and
expose SPI0 pins on the Raspberry Pi compatible expansion header.
The A13-OLinuXino-Micro board also can be used.

It is useful to be able to build SPL for sandbox. It provides additional
build coverage and allows SPL features to be tested in sandbox. However
it does not need worthwhile to always create an SPL build. It nearly
doubles the build time and the feature is (so far) seldom used.
So for now, create a separate build target for sandbox SPL. This allows
experimentation with this new feature without impacting existing workflows.

As the help message of CONFIG_BOOTDELAY says, CONFIG_BOOTDELAY=-2
means the autoboot with no delay, with no abort check even if
CONFIG_ZERO_BOOTDELAY_CHECK is defined.
To sum up, the autoboot behaves as follows:
[1] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=y
autoboot with no delay, but you can abort it by key input
[2] CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n
autoboot with no delay, with no check for abort
[3] CONFIG_BOOTDELAY=-1
disable autoboot
[4] CONFIG_BOOTDELAY=-2
autoboot with no delay, with no check for abort
As you notice, [2] and [4] come to the same result, which means we
do not need CONFIG_ZERO_BOOTDELAY_CHECK. We can control all the
cases only by CONFIG_BOOTDELAY, like this:
[1] CONFIG_BOOTDELAY=0
autoboot with no delay, but you can abort it by key input
[2] CONFIG_BOOTDELAY=-1
disable autoboot
[3] CONFIG_BOOTDELAY=-2
autoboot with no delay, with no check for abort
This commit converts the logic as follow:
CONFIG_BOOTDELAY=0 && CONFIG_ZERO_BOOTDELAY_CHECK=n
--> CONFIG_BOOTDELAY=-2

Before this patch, when booting from MMC (no filesystem), the SPL
loaded U-Boot from a fixed offset.
It will now load U-Boot from an offset of 256kB (which is 4 times the
padded SPL image) in the third partition.
This behaviour is similar to what the vendor SPL (based on
U-Boot 2013.01) does, and allows to directly 'dd' the
u-boot-with-spl.sfp file to the A2 partition.

V2: Update the defconfig as per Tom's request
P2771-0000 is a P3310 CPU board married to a P2597 I/O board. The
combination contains SoC, DRAM, eMMC, SD card slot, HDMI, USB micro-B
port, Ethernet, USB3 host port, SATA, PCIe, and two GPIO expansion
headers.
Currently, due to U-Boot's level of support for Tegra186, the only
features supported by U-Boot are the console UART and the on-board eMMC.
Additional features will be added over time.
U-Boot has so far been tested by replacing the kernel image on the device
with a U-Boot binary. It is anticipated that U-Boot will eventually
replace the CCPLEX bootloader binary, as on previous chips. This hasn't
yet been tested.

This adds the bare minimum code to support Tegra186, with UART and eMMC
working.
The empty gpio.h is required because <asm/gpio.h> includes it. A future
cleanup round may be able to solve this for all Tegra generations at once.
mach-tegra/Makefile is adjusted not to compile anything for Tegra186, but
instead to defer everything to mach-tegra/tegra186/Makefile. This allows
the SoC code to pick-and-choose which of the C files in the "common"
mach-tegra/ directory to compile in based on the SoC's needs. Most of the
code is not valid for Tegra186, and this approach removes the need for
mach-tegra/Makefile to contain many SoC-specific ifdefs. This approach
may be applied to all other Tegra SoCs in a future cleanup round.
board186.c is introduced to replace board.c and board2.c. These files
currently contain a slew of SoC- and board-specific code that is not
valid for Tegra186. This approach avoids adding yet more ifdefs to those
files. A future cleanup round may refactor most of board*.c into board-/
SoC-specific functions files thus allowing the top-level functions like
board_init_early_f to be shared again.

Updates configs/am43xx_evm.h to use CONFIG options from
SOC specific Kconfig file for various calculations.
On AM43x devices, the address of SPL entry point depends on
the device type, i.e. whether it is secure or non-secure.
Further, for non-secure devices, the SPL entry point is different
between USB HOST boot mode, other "memory" boot modes (MMC, NAND)
and "peripheral" boot modes (UART, USB)
To add to the complexity, on secure devices, in addition to the
above differences, the SPL entry point can change because of the
space occupied by other components (other than u-boot or spl)
that go into a secure boot image.
To prevent the user from having to modify source files every time
any component of the secure image changes, the value of
CONFIG_SPL_TEXT_BASE has been set using a Kconfig option that
is supplied in the am43xx_*_defconfig files
Using the CONFIG options also enables us to do away with some
compile time flags that were used to specify CONFIG_SPL_TEXT_BASE
for different boot modes.
On QSPI devices, the same problem described above occurs w.r.t. the
address of the u-boot entry point in flash, when booting secure
devices. To handle this, CONFIG_SYS_TEXT_BASE is also setup via
a Kconfig option and the defconfig files.

functions and since exynos5 does not use DM in SPL, these functions come

The current SPL header, created by the 'mksunxiboot' tool, has size
32 bytes. But the code in the boot ROM stores the information about
the boot media at the offset 0x28 before passing control to the SPL.
For example, when booting from the SD card, the magic number written
by the boot ROM is 0. And when booting from the SPI flash, the magic
number is 3. NAND and eMMC probably have their own special magic
numbers too.
Currently the corrupted byte is a part of one of the instructions in
the reset vectors table:
b reset
ldr pc, _undefined_instruction
ldr pc, _software_interrupt <- Corruption happens here
ldr pc, _prefetch_abort
ldr pc, _data_abort
ldr pc, _not_used
ldr pc, _irq
ldr pc, _fiq
In practice this does not cause any visible problems, but it's still
better to fix it. As a bonus, the reported boot media type can be
later used in the 'spl_boot_device' function, but this is out of
the scope of this patch.

Now that rpi_*defconfig and Kconfig (rather than the config header file)
provide the identity of the build, we don't need to separate config
headers and board directories for each RPi variant. Set CONFIG_SYS_BOARD
and CONFIG_SYS_CONFIG_NAME so that we can get rid of the duplication. This
requires a tiny number of extra ifdefs in the config header.
The only disadvantage of this approach is that the $board/$board_name
environment variables aren't as descriptive as they used to be. This isn't
really an issue because those only exist to allow scripts to create DTB
filenames at runtime. However, the RPi board code already sets $fdtfile to
something more accurate based on FW-reported board ID anyway.
While at it, unify some Kconfig select options, and add a MAINTAINERS
entry for bcm283x too.

On all Pis so far, the VC FW provides a short stub to set up the ARM CPU
before entering the kernel (a/k/a U-Boot for us). This feature is not
currently supported by the VC FW when booting in 64-bit mode. However,
this feature will likely appear in the near future, and this U-Boot port
assumes that such a feature is in place. Without that feature, or a
temporary workaround described below, U-Boot will not boot.
Once the VC FW does provide the ARM stub, u-boot.bin built for rpi_3 can
be used drectly as kernel7.img, in the same way as any other RPi port. The
following config.txt is required:
# Fix mini UART input frequency, and setup/enable up the UART.
# Without this option, U-Boot will not boot, even if you don't care
# about the serial console. This option will always be required for
# all RPi3 use-cases, unless the PL011 UART is used, which is not
# yet supported by rpi_3* builds of U-Boot.
enable_uart=1
# Boot in AArch64 (64-bit) mode.
# It is possible that a future VC FW will remove the need for this
# option, instead auto-setting 32-/64-bit mode based on the "kernel"
# filename present on the SD card.
arm_control=0x200
Prior to the VC FW providing the ARM boot stub, you can use the following
steps to build an equivalent stub into the U-Boot binary:
git clone https://github.com/swarren/rpi-3-aarch64-demo.git \
../rpi-3-aarch64-demo
(cd ../rpi-3-aarch64-demo && ./build.sh)
Build U-Boot for rpi_3 in the usual way
cat ../rpi-3-aarch64-demo/armstub64.bin u-boot.bin > u-boot.bin.stubbed
Use u-boot.bin.stubbed as kernel7.img on the Pi SD card.
In this case, the following additional entries are required in config.txt:
# Tell the FW to load the kernel image at address 0, the reset vector.
kernel_old=1

The Raspberry Pi 3 contains a BCM2837 SoC. The BCM2837 is a BCM2836 with
the CPU complex swapped out for a quad-core ARMv8. This can operate in 32-
or 64-bit mode. 32-bit mode is the current default selected by the
VideoCore firmware on the Raspberry Pi 3. This patch adds a 32-bit port of
U-Boot for the Raspberry Pi 3.
>From U-Boot's perspective, the only delta between the RPi 2 and RPi 3 is a
change in usage of the SoC UARTs. On all previous Pis, the PL011 was the
only UART in use. The Raspberry Pi 3 adds a Bluetooth module which uses a
UART to connect to the SoC. By default, the PL011 is used for this purpose
since it has larger FIFOs than the other "mini" UART. However, this can
be configured via the VideoCore firmware's config.txt file. This patch
hard-codes use of the mini UART in the RPi 3 port. If your system uses the
PL011 UART for the console even on the RPi 3, please use the RPi 2 U-Boot
port instead. A future change might determine which UART to use at
run-time, thus allowing the RPi 2 and RPi 3 (32-bit) ports to be squashed
together.
The mini UART has some limitations. One externally visible issue in the
BCM2837 integration is that the UART divides the SoC's "core clock" to
generate the baud rate. The core clock is typically variable, and under
control of the VideoCore firmware for thermal management reasons. If the
VC FW does modify the core clock rate, UART communication will be
corrupted since the baud rate will vary from the expected value. This was
not an issue for the PL011 UART, since it is fed by a fixed 3MHz clock. To
work around this, the VideoCore firmware can be told not to modify the SoC
core clock. However, the only way this can happen and be thermally safe is
to limit the core clock to a low/minimum frequency. This leaves
performance on the table for use-cases that don't care about a UART
console. Consequently, use of the mini UART console must be explicitly
requested by entering the following line into config.txt:
enable_uart=1
A recent version of the VC firmware is required to ensure that the mini
UART is fully and correctly initialized by the VC FW; at least

core clock See: https://github.com/raspberrypi/firmware/issues/572".

Commit d085ecd61b ("ARM: uniphier: switch to raw U-Boot image")
claimed that u-boot-with-spl.bin would be useful in its commit log,
but it was not available because the commit missed to define
CONFIG_SPL_MAX_SIZE. Without it, CONFIG_SPL_PAD_TO is not defined
either (see include/config_fallbacks.h). So, the SPL image is not
padded correctly.

Currently, CONFIG_BCM2835 is defined for all BCM283x builds and _BCM2836
is defined when building for that SoC. That means there isn't a single
define that means "exactly BCM2835". This will complicate future patches
where BCM2835-vs-anything-else needs to be determined simply.
Modify the code to define one or the other of CONFIG_BCM2835/BCM2836 so
future patches are simpler.

Commit 1e3d640316 (ARM: sheevaplug: redefine MTDPARTS) changed the partition
layout (without any description why), but didn't change the offset/size to
load the kernel from or the root=/dev/mtdblockX in the bootargs.
The 3MB forseen for a kernel is furthermore too little. A 4.4 build of
mvebu_v5_defconfig is 3.6MB:
-rw-r--r-- 1 peko peko 3.6M Jan 16 20:24 uImage.kirkwood-sheevaplug
When device tree support for sheevaplug was added to the kernel in commit
ee514b381e (ARM: Kirkwood: Add dts files for Sheevaplug and eSATA
Sheevaplug) a default flash partition layout (used if mtdparts= isn't passed
on the command line / CONFIG_MTD_CMDLINE_PARTS isn't enabled) with 1MB for
u-boot / environment, 4MB for the kernel and the rest for the rootfs, so use
that layout here and adjust the kernel loading to match.

Now everything is done to load a raw U-Boot proper image instead of
an mkimage-processed one (as far as I tested on NAND, eMMC, NOR).
The SPL already knows the load address of the U-Boot proper without
parsing its uImage header because the load address is defined by
CONFIG_SYS_TEXT_BASE, assuming that the two images are generated from
the same build.
My main motivation of this switch is to use u-boot-with-spl.bin, a
concatenation of u-boot-spl.bin and u-boot.bin. (I wish there were
a concatenation of u-boot-spl.bin and u-boot.img...) Anyway, this
commit would be useful for one-shot image burn.

The K2 linux drivers for PCIe and NetCP (1G, 10G) requires serdes
firmwares. These requires firmware to be available early through the boot
process in some cases to satisfy firmware requests from driver. Hence use
a small initramfs to provide the same and update boot env to accommodate
this in the boot flow. This method is used when rootfs is nfs and ubifs.
This fs contains just lib/firmware folder with all required firmware.
When rootfs is on initramfs, then the filesystem has the firmware under
lib/firmware and this early initramfs is not required and is not used.
