Bernhard Nortmann 0751b13806 sunxi: Enable CONFIG_SYS_64BIT_LBA when AHCI is used
Due to absence of CONFIG_SYS_64BIT_LBA, u-boot-sunxi currently has
no support for the (GPT) partioning scheme of large disks > 2TB.
While the AHCI driver seems to handle this nicely, the problem is
that lbaint_t values get truncated to 32-bit.

This patch sets CONFIG_SYS_64BIT_LBA from sunxi_common.h for all
SoCs that support AHCI (CONFIG_SUNXI_AHCI).

Hans de Goede a8552c7c9b console: Fix pre-console flushing via cfb_console being very slow
On my A10 OlinuxIno Lime I noticed a huge (5+ seconds) delay coming from
console_init_r. This turns out to be caused by the preconsole buffer flushing
to the cfb_console. The Lime only has a 16 bit memory bus and that is already
heavy used to scan out the 1920x1080 framebuffer.

The problem is that print_pre_console_buffer() was printing the buffer once
character at a time and the cfb_console code then ends up doing a cache-flush
for touched display lines for each character.

This commit fixes this by first building a 0 terminated buffer and then
printing it in one puts() call, avoiding unnecessary cache flushes.

This changes the time for the flush from 5+ seconds to not noticable.

The downside of this approach is that the pre-console buffer needs to fit
on the stack, this is not that much to ask since we are talking about plain
text here. This commit also adjusts the sunxi CONFIG_PRE_CON_BUF_SZ to
actually fit on the stack. Sunxi currently is the only user of the pre-console
code so no other boards need to be adjusted.

Siarhei Siamashka 77ef136950 sunxi: Machine id hack to prevent loading buggy sunxi-3.4 kernels
Right now U-Boot supports the CONFIG_OLD_SUNXI_KERNEL_COMPAT option,
which makes it go out of its way in limiting the selection of PLL clock
frequencies and PMIC voltages in order not to upset outdated buggy
sunxi-3.4 kernel releases. And if the CONFIG_OLD_SUNXI_KERNEL_COMPAT
option is not set, then booting such old kernels exhibits various
failures at runtime. This is very user unfriendly, and there were
already several incidents when people wasted their time being hit
by these runtime failures and trying to debug them.

The right solution is not to add hacks and workarounds to the mainline
U-Boot, but to fix these bugs in the sunxi-3.4 kernel. And in fact,
the updated sunxi-3.4 kernels already exist. Still we need to follow
the 'Principle of Least Surprise' and U-Boot needs to ensure that
the old buggy kernels are not getting happily booted when the
CONFIG_OLD_SUNXI_KERNEL_COMPAT option is not set. And this patch
addresses this particular issue.

This patch makes U-Boot store the 'compatibility revision' number in
the top 4 bits of the machine id and pass it to the kernel. The old
buggy kernels will fail to load with a very much googlable error
message on the serial console (the "r1 = 0x100010bb" part of it):

  "Error: unrecognized/unsupported machine ID (r1 = 0x100010bb)"

This error message can be documented in the linux-sunxi wiki with
proper explanations about how to resolve this situation and where
to get the necessary bugfixes for the sunxi-3.4 kernel.

The fixed sunxi-3.4 kernels implement a revision compatibility check
and clear the top 4 bits of the machine id if everything is alright.
By accepting the machine id with the bits 31:28 set to 1, the sunxi-3.4
kernel effectively certifies that it has the PLL5 clock speed and
AXP209 DCDC3 voltage fixes applied.

It is still possible to set the CONFIG_OLD_SUNXI_KERNEL_COMPAT option
in U-Boot if the user desires to use an outdated unpatched sunxi-3.4
kernel.

Hans de Goede f3133962f4 sunxi: Set the /chosen/stdout-path fdt property for sunxi boards
While discussing with some people how to get the Linux kernel to do the
right thing wrt sending output to both the serial console and the
hdmi out / lcd screen when booting on ARM devices, Grant Likely pointed out
that there already is a solution for this.

All we need to do is set the /chosen/stdout-path fdt property, and if no
console= arguments were specified on the kernel commandline the kernel
will honor this and add this device as a console (next to the primary
video output on hdmi).

And u-boot already has support for setting this, all we need to do is
define OF_STDOUT_PATH and then everything will just work ootb, without
people needing to meddle with adding console= arguments in extlinux.conf .

Hans de Goede 5633a296eb sunxi: video: Do not use CONFIG_SYS_MEM_TOP_HIDE for the framebuffer
Do not use CONFIG_SYS_MEM_TOP_HIDE for the framebuffer, instead override
board_get_usable_ram_top to make sure that u-boot is not relocated into the
area where we want to use the framebuffer, and patch the devicetree from
sunxi_simplefb_setup() to tell the kernel to not touch the framebuffer.

This makes u-boot properly see the framebuffer as dram, and initalize the
level 2 cache for it, fixing the very slow cfb scrolling problem.

As an added bonus this stops us from reserving the framebuffer when simplefb
is not used because an older kernel is booted, or hdp is used and no hdmi
cable was plugged in, freeing up the memory for kernel use in these cases.

Hans de Goede b56f6e2b4e sunxi: Restore lowlevel_init usage
2 recent sunxi changes have removed the usage of lowlevel_init by moving some
code around and then setting CONFIG_SKIP_LOWLEVEL_INIT.
This is problematic for 2 reasons:

1) It does not just stop s_init from being called, it also stops
cpu_init_cp15 from getting called, which is undesirable.

2) We want u-boot.bin to be usable standalone, without SPL, some people e.g.
use an upstream u-boot.bin together with Allwinner's boot0 loader. So
u-boot.bin must (re)initialize the gpios, timer, etc.

Siarhei Siamashka f0ce28e9ed sunxi: Fix CONFIG_UART0_PORT_F build and add it to menuconfig
The CONFIG_UART0_PORT_F option has been supported since
    http://git.denx.de/?p=u-boot.git;a=commit;h=ff2b47f6a9cc1025

This option is primarily useful only for low level u-boot debugging
on tablets, where normal UART0 is difficult to access and requires
device disassembly and/or soldering.

This patch now allows it to be selected from menuconfig. A dependency on
SPL_FEL is added because u-boot does not support booting from NAND yet
and also booting from SD card is impossible when a MicroSD breakout board
is plugged into the SD slot.

Additionally a compilation problem is fixed:

common/spl/built-in.o: In function `spl_mmc_load_image':
/tmp/u-boot-sunxi/common/spl/spl_mmc.c:94: undefined reference to `mmc_initialize'
/tmp/u-boot-sunxi/common/spl/spl_mmc.c:96: undefined reference to `find_mmc_device'
/tmp/u-boot-sunxi/common/spl/spl_mmc.c:104: undefined reference to `mmc_init'
scripts/Makefile.spl:206: recipe for target 'spl/u-boot-spl' failed

Add simplefb support, note this depends on the kernel having support for
the clocks property which has recently been added to the simplefb devicetree
binding.

Luc Verhaegen 7f2c521f90 sunxi: video: Add cfb console driver for sunxi
This adds a fixed mode hdmi driver for the sunxi platform. The fixed
mode is a relatively safe 1024x768, more complete EDID handling is
currently not provided. Only HDMI is supported today.

This code is enabled when HPD detects an attached monitor.

Current config is such that 8MB is shaved off at the top of the RAM.
This avoids several memory handling issues, most significant is the fact
that on linux on ARM you are not allowed to remap known RAM as IO. A
clued in display driver will be able to recycle this reserved RAM in
future though.

cfbconsole was chosen as it provides the most important functionality: a
working u-boot console, allowing for the debugging of certain issues
without the need for a UART.

Simon Glass 1a81cf8399 dm: sunxi: Add support for serial using driver model
Add a driver for the designware serial UART used on sunxi. This just
redirects to the normal ns16550 driver.

Add a stdout-path to the device tree so that the correct UART is chosen.

Simon Glass 7aa9748584 dm: sunxi: Modify the GPIO driver to support driver model
This adds driver model support to the sunxi GPIO driver, using the device
tree to trigger binding of the driver. The driver will still operate
without driver model too.
