Marek Vasut d68f4da2fa serial: powerpc: Implement CONFIG_SERIAL_MULTI into mpc8260 serial drivers
Implement support for CONFIG_SERIAL_MULTI into both SCC and SMC mpc8260
serial drivers. These drivers were so far only usable directly, but this
patch also adds support for the multi method. This allows using more than
one serial driver alongside the mpc8260 drivers. Also, add a weak
implementation of default_serial_console() returning this driver.

Marek Vasut 918327c8f0 serial: mpc512x: Move serial registration from serial_initialize()
Move the registration of serialN_device ports from default
serial_initialize() into driver specific function called from
serial_initialize(). This slims down the serial_initialize() call
to a bare tracker of all possible serial port registration routines
in U-Boot.

The newly implemented mpc512x_serial_initialize() function, which is
implemented inside of the mpc512x serial driver allows encapsulation
of serialN_device within the mpc512x serial driver itself.

Also, remove the exports of serialN_device from include/serial.h
as they are no longer needed. This is simply because the implementation of
default_serial_console() is wrapped into the mpx512x serial driver and
the default console is picked by CONFIG_SERIAL<N> macro in config file.

Anatolij Gustschin e5ab702a6c powerpc: re-add bi_ip_addr to bd_t struct
Since commit 50a47d0523
(net: punt bd->bi_ip_addr) booting old 2.4.x ppc kernels
is broken due to changed offsets of the fields in struct bd_t.
Offsets of the fields after removed bi_ip_addr are wrong,
causing wrong bus clocks and console baudrate configurations
and various other issues. Re-add the bi_ip_addr field to preserve
backward compatibility with older ppc kernels. Setting bi_ip_addr
in board.c is not really needed, grepping in the 2.4 linux tree
shows that bi_ip_addr is not accessed there. Adding bi_ip_addr
to struct bd_t for other arches isn't needed it seems. bd_t is
not used by other arches in the 2.4 linux tree.

Scott Wood 33eee330cc powerpc/fsl-corenet: work around erratum A004510
Erratum A004510 says that under certain load conditions, modified
cache lines can be discarded, causing data corruption.

To work around this, several CCSR and DCSR register updates need to be
made in a careful manner, so that there is no other transaction in
corenet when the update is made.

The update is made from a locked cacheline, with a delay before to flush
any previous activity, and a delay after to flush the CCSR/DCSR update.
We can't use a readback because that would be another corenet
transaction, which is not allowed.

We lock the subsequent cacheline to prevent it from being fetched while
we're executing the previous cacheline.  It is filled with nops so that a
branch doesn't cause us to fetch another cacheline.

Ordinarily we are running in a cache-inhibited mapping at this point, so
we temporarily change that.  We make it guarded so that we should never
see a speculative load, and we never do an explicit load.  Thus, only the
I-cache should ever fill from this mapping, and we flush/unlock it
afterward.  Thus we should avoid problems from any potential cache
aliasing between inhibited and non-inhibited mappings.

NOTE that if PAMU is used with this patch, it will need to use a
dedicated LAW as described in the erratum.  This is the responsibility
of the OS that sets up PAMU.

Liu Gang b5f7c8732a powerpc/corenet_ds: Master module for boot from PCIE
For the powerpc processors with PCIE interface, boot location can be
configured from one PCIE interface by RCW. The processor booting from PCIE
can do without flash for u-boot image. The image can be fetched from another
processor's memory space by PCIE link connected between them.

The processor booting from PCIE is slave, the processor booting from normal
flash memory space is master, and it can help slave to boot from master's
memory space.

When boot from PCIE, slave's core should be in holdoff after powered on for
some specific requirements. Master will release the slave's core at the
right time by PCIE interface.

Environment and requirement:

master:
    1. NOR flash for its own u-boot image, ucode and ENV space.
    2. Slave's u-boot image is in master NOR flash.
    3. Normally boot from local NOR flash.
    4. Configure PCIE system if needed.
slave:
    1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
    2. Boot location should be set to one PCIE interface by RCW.
    3. RCW should configure the SerDes, PCIE interfaces correctly.
	4. Must set all the cores in holdoff by RCW.
	5. Must be powered on before master's boot.

For the master module, need to finish these processes:
    1. Initialize the PCIE port and address space.
    2. Set inbound PCIE windows covered slave's u-boot image stored in
       master's NOR flash.
	3. Set outbound windows in order to configure slave's registers
	   for the core's releasing.
    4. Should set the environment variable "bootmaster" to "PCIE1", "PCIE2"
	   or "PCIE3" using the following command:

			setenv bootmaster PCIE1
			saveenv

Return type of in_8, in_be16 and in_le16 should not be'int'. Update it to type
u8/u16/u32.
Although 'unsigned' for in_be32 and in_le32 is correct. But to make return type
uniform across the file changed to u32

Similarly, parameter passed to out_8, out_be16, out_le16 ,out_be32 & out_le32
should not be 'int'.Change it to type u8/u16/u32.

Timur Tabi 5c5befda58 powerpc/85xx: use CONFIG_SYS_FSL_PCIE_COMPAT macro when setting the PCI LIODNs
The SET_PCI_LIODN() macro takes a compatible property string as a parameter, so that it knows
which PCI device tree node to look for.  The calls to these macros are using a hard-coded string,
but we already have the CONFIG_SYS_FSL_PCIE_COMPAT macro which contains the same string, so we
should use that.

addrmap_phys_to_virt() converts a physical address (phys_addr_t) to a
virtual address, so it should return a pointer instead of an unsigned long.
Its counterpart, addrmap_virt_to_phys(), takes a pointer, so now they're
orthogonal.

The only caller of addrmap_phys_to_virt() converts the return value to
a pointer anyway.

Debugging of e500 and e500v1 processer requires debug exception vecter (IVPR +
IVOR15) to have valid and fetchable OP code.

1) While executing in translated space (AS=1), whenever a debug exception is
generated, the MSR[DS/IS] gets cleared i.e. AS=0 and the processor tries to
fetch an instruction from the debug exception vector (IVPR + IVOR15); since now
we are in AS=0, the application needs to ensure the proper TLB configuration to
have (IVOR + IVOR15) accessible from AS=0 also.
Create a temporary TLB in AS0 to make sure debug exception verctor is
accessible on debug exception.

2) Just after relocation in DDR, Make sure IVPR + IVOR15 points to valid opcode

Liu Gang 5056c8e068 powerpc/corenet_ds: Slave core in holdoff when boot from SRIO
When boot from SRIO, slave's core can be in holdoff after powered on for
some specific requirements. Master can release the slave's core at the
right time by SRIO interface.

Master needs to:
	1. Set outbound SRIO windows in order to configure slave's registers
	   for the core's releasing.
	2. Check the SRIO port status when release slave core, if no errors,
	   will implement the process of the slave core's releasing.

Liu Gang 5ffa88eca7 powerpc/corenet_ds: Master module for boot from SRIO
For the powerpc processors with SRIO interface, boot location can be configured
from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash
for u-boot image. The image can be fetched from another processor's memory
space by SRIO link connected between them.

The processor boots from SRIO is slave, the processor boots from normal flash
memory space and can help slave to boot from its memory space is master.
They are different environments and requirements:

master:
	1. NOR flash for its own u-boot image, ucode and ENV space.
	2. Slave's u-boot image in master NOR flash.
	3. Normally boot from local NOR flash.
	4. Configure SRIO switch system if needed.
slave:
	1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
	2. Boot location should be set to SRIO1 or SRIO2 by RCW.
	3. RCW should configure the SerDes, SRIO interfaces correctly.
	4. Slave must be powered on after master's boot.

For the master module, need to finish these processes:
	1. Initialize the SRIO port and address space.
	2. Set inbound SRIO windows covered slave's u-boot image stored in
	   master's NOR flash.
	3. Master's u-boot image should be generated specifically by
	   make xxxx_SRIOBOOT_MASTER_config
	4. Master must boot first, and then slave can be powered on.

Kyle Moffett 01baa05643 powerpc: Minimal private libgcc to build on Debian
Standard Debian powerpc and powerpcspe systems only include hard-float
libgcc in their native compilers, which causes scary build warnings when
building U-Boot.

Debian and other PowerPC-supporting distributions used to provide libgcc
and other libraries in a "nof" (soft-float) form in the "multilib"
packages.  As they were completely unused by the distribution and
therefore tended to be very buggy it was decided to save some time on
the part of the maintainers and build-servers by removing them.

Admittedly, right now the linker warnings do not indicate any problems,
as the included routines do not use any floating point at all.

The concern is that if floating-point code were ever added it might
cause hard-float code to be unexpectedly included in U-Boot without
generating a hard error.  This would cause unexplained crashes or
indeterminate results at runtime.

The easiest way to resolve this is to borrow the routines that U-Boot
needs from the Linux kernel, which has the same issue.

Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3().
They were borrowed from arch/powerpc/kernel/misc_32.S as of v2.6.38-rc5,
commit 85e2efbb1db9a18d218006706d6e4fbeb0216213, and are GPLv2+.

The Makefile framework was copied from the U-Boot ARM port.

Timur Tabi cc15df57b1 powerpc/85xx: verify the localbus device tree address before booting the OS
The localbus controller node in the device tree is typically a root node,
even though the controller is part of CCSR.  If we were to put the lbc
node under the SOC node, then the 'ranges' property in the lbc node would
translate through the 'ranges' property of the parent SOC node, and we
don't want that.

Since the lbc is a separate node, it's possible for the 'reg' property to
be wrong.  This happened with the original version of p1022ds.dts, which
used a 32-bit value in the 'reg' address, instead of a 36-bit address.

Timur Tabi f2717b47ea powerpc/85xx: clean up and document the QE/FMAN microcode macros
Several macros are used to identify and locate the microcode binary image
that U-boot needs to upload to the QE or Fman.  Both the QE and the Fman
use the QE Firmware binary format to package their respective microcode data,
which is why the same macros are used for both.  A given SOC will only have
a QE or an Fman, so this is safe.

Unfortunately, the current macro definition and usage has inconsistencies.
For example, CONFIG_SYS_FMAN_FW_ADDR was used to define the address of Fman
firmware in NOR flash, but CONFIG_SYS_QE_FW_IN_NAND contains the address
of NAND.  There's no way to know by looking at a variable how it's supposed
to be used.

In the future, the code which uploads QE firmware and Fman firmware will
be merged.

when setting MSR[FP], and can be cleared when clearing MSR[FP].
Alternatively, the bit can be set once at boot time, and never cleared.
There will be no performance degradation due to setting this bit.

Che-Liang Chiou d3983ee853 font: split font data from video_font.h
While video_font.h is useful even without referencing the font data, it
is not possible to be included multiple times because it defines font
data array right in the header.

This patch splits the font data array into video_font_data.h and so now
video_font.h can be included multiple times.  This at least solves the
code duplication in board/mcc200/lcd.c.

Specifically, how we determine the size of TLB entries we support in the

(TLBnPS - TLB n Page size) instead of via TLBnCFG.

On some Freescale systems (e.g. those booted from the on-chip ROM), the
TLB that covers the boot page can also cover CCSR, which breaks the CCSR
relocation code.  To fix this, we resize the boot page TLB so that it only
covers the 4KB boot page.

Verify that CCSR is actually located where it is supposed to be before
we relocate it.  This is useful in detecting U-Boot configurations that
are broken (e.g. an incorrect value for CONFIG_SYS_CCSRBAR_DEFAULT).
If the current value is wrong, we enter an infinite loop, which is handy
for debuggers.

- no spaces at the start of a line
  (accepted in multi-line #if's)
- Macros with complex values

Wolfgang Denk cca4e4aec1 Reduce build times
U-Boot Makefiles contain a number of tests for compiler features etc.
which so far are executed again and again.  On some architectures
(especially ARM) this results in a large number of calls to gcc.

This patch makes sure to run such tests only once, thus largely
reducing the number of "execve" system calls.

Example: number of "execve" system calls for building the "P2020DS"
(Power Architecture) and "qong" (ARM) boards, measured as:
	-> strace -f -e trace=execve -o /tmp/foo ./MAKEALL <board>
	-> grep execve /tmp/foo | wc -l

	Before: After:	Reduction:
==================================
P2020DS 20555	15205	-26%
qong	31692	14490	-54%

As a result, built times are significantly reduced, typically by
30...50%.

Bernhard Kaindl 9d256b67f6 powerpc/lib/board.c: Call run_post(POST_ROM) before relocating
The call to run_post(POST_ROM) which can run the POST memory test
is currently called too late when gd has already been copied to DRAM.

This results in failure to boot Linux after a POST_ROM memory test
tested all RAM while gd was already relocated to DRAM due to gd being
overwritten by the POST_ROM memory test.

Support this by moving the call to run_post(POST_ROM) to run earlier,
before U-Boot has started to move data to DRAM (from late board_init_f
to early board_init_f) where DRAM is initialized, but not used yet.

This allows that an POST memory test can test the whole DRAM,
including the area where the board info struct is located.

Kyle Moffett 710308ee18 mpc85xx: Add inline GPIO acessor functions
To ease the implementation of other MPC85xx board ports, several common
GPIO helpers are added to <asm/mpc85xx_gpio.h>.

Since each of these compiles to no more than 4-5 instructions it would
be very inefficient to call them out of line, therefore we put them
entirely in the header file.

The HWW-1U-1A board port which these were written for strongly prefers
to set multiple GPIOs as a single batch operation, so the API is
designed around that basis.

To assist other board ports, a small set of wrappers are used which
provides a standard gpio_request() interface around the MPC85xx-specific
functions.  This can be enabled with CONFIG_MPC85XX_GENERIC_GPIO

was creating the phandle properties manually.  Instead, change it to use
fdt_create_phandle().

Haiying Wang 34fdbdf8d9 powerpc/p3041: fixup portal config info
P3041 has 10 qman portals, we need to configure all of them:
* As there are only 4 physical cores sdest can only be 0 to 3
* We assign dqrr & frame data LIODNs for all portals so if they
  are utilized the proper mapping tables can be setup uniquely
  (PAMU stashing)
* We set Portal 6-10 to LIODN offsets 1-5 as the global LIODN
  assignments are tuned around an assumption of at most 5
  partitions.

Xie Xiaobo ae2044d8b3 powerpc/mpc8536ds: Add eSPI support for MPC8536DS
1. The SD_DATA[4:7] signals are shared with the SPI chip selects on 8536DS,
   so don't set MPC85xx_PMUXCR_SD_DATA that config eSDHC data bus-width
   to 4-bit and enable SPI signals.
2. Add eSPI controller and SPI-FLASH definition.

Becky Bruce 1605cc9e1b powerpc/mpc86xx: Disable translation for BAT setup
We really shouldn't be overwriting bat registers with translation enabled,
especially when we're executing code using one of them for translating
the current instruction stream.  Instead, disable address translation
while doing the final BAT setup.

In order to do this, setup_bats has to move back to asm code, because we
require translation to be enabled to have a stack for C code.  The yucky
thing about that is that the assembler doesn't like ULL so we have to
switch to using HIGH/LOW pairs for physical addresses that are > 32 bits
in length.

Timur Tabi 3038171628 powerpc/85xx: fix null pointer dereference when init the SGMII TBI PHY
Function dtsec_configure_serdes() needs to know where the TBI PHY registers
are in order to configure SGMII for proper SerDes operation.

During SGMII initialzation, fm_eth_init_mac() passing NULL for 'phyregs'
when it called init_dtsec(), because it was believed that phyregs was not
used.  In fact, it is used by dtsec_configure_serdes() to configure the TBI
PHY registers.

We also need to define the PHY registers in struct fm_mdio.

York Sun 6f5e1dc531 powerpc/8xxx: Add support for interactive DDR programming interface
Interactive DDR debugging provides a user interface to view and modify SPD,
DIMM parameters, board options and DDR controller registers before DDR is
initialized. With this feature, developers can fine-tune DDR for board
bringup and other debugging without frequently having to reprogram the flash.

To enable this feature, define CONFIG_FSL_DDR_INTERACTIVE in board header
file and set an environment variable to activate it. Syntax:

setenv ddr_interactive on

After reset, U-boot prompts before initializing DDR controllers
FSL DDR>

The available commands are
print      print SPD and intermediate computed data
reset      reboot machine
recompute  reload SPD and options to default and recompute regs
edit       modify spd, parameter, or option
compute    recompute registers from current next_step to end
next_step  shows current next_step
help       this message
go         program the memory controller and continue with u-boot

The first command should be "compute", which reads data from DIMM SPDs and
board options, performs the calculation then stops before setting DDR
controller. A user can use "print" and "edit" commands to view and modify
anything. "Go" picks up from current step with any modification and
compltes the calculation then enables the DDR controller to continue u-boot.
"Recompute" does it over from fresh reading.

This is long over due.  All but two net drivers have been converted, but
those have now been dropped.

The only thing left to do is actually delete all references to NET_MULTI
and code that is compiled when that is not defined.  So here we scrub the
core code.
