This adds the required GPIO and pinmux configuration to make eMMC / SD work
on Seaboard.

This adds support for changing pinmux functions of pin groups. This is done
by defining a PMUX_FUNC_... enum which can be used to select the function for
each group using pinmux_set_func(). It is also possible to enable
pullup/pulldown, and the existing tristate functionality is retained.
Also provided is a means of configuring a list of pingroups by providing a
configuration table to pinmux_config_table().

The pin groupings are better named PINGRP, since on Tegra2 they refer to
multiple pins.
Sorry about this, but better to get it right now when there is only a small
amount of code affected.

This adds most of the clock functions required by board and driver code:
-query and adjust peripheral clocks
-query and adjust PLLs
-reset and enable control
These functions are plumbed in as required.

This removes clock_init() and pinmux_init() which are names better suited
to those respective modules. By moving board_init_f() to the bottom of the
file we can remove the need for so many functions in the board.h header file.
The only clock/pinmux/gpio init we need to do prior to relocation is
for the UART.

Rename CLOCK_PLL_ID to CLOCK_ID which takes account of the fact that the
code now deals with both PLL clocks and source clocks.
This also tidied up the assert() to match the one sent upstream, and fixes
an error in the PWM id.

In some cases, saving data in RAM as a file with FAT format is required.
This patch allows the file to be written in FAT formatted partition.
The usage is similar with reading a file.
First, fat_register_device function is called before file_fat_write function
in order to set target partition.
Then, file_fat_write function is invoked with desired file name,
start ram address for writing data, and file size.

This adds support for a new environment variable called 'fdtcontroladdr'. If
defined, the hex address is used as the address of the control fdt for U-Boot.
Note: I have not changed CONFIG_PRAM section as I already have an
outstanding patch on that.

This locates the device tree either embedded within U-Boot or attached to the
end as a separate binary.
When CONFIG_OF_CONTROL is defined, U-Boot requires a valid fdt. A check is
provided for this early in initialisation.

This library provides useful functions to drivers which want to use
the fdt to control their operation. Functions are provided to:
- look up and enumerate a device type (for example assigning i2c bus 0,
i2c bus 1, etc.)
- decode basic types from the fdt, like addresses and integers
While this library is not strictly necessary, it helps to minimise the
changes to a driver, in order to make it work under fdt control. Less
code is required, and so the barrier to switch drivers over is lower.
Additional functions to read arrays and GPIOs could be made available
here also.

This adds support for an FDT to be build as a separate binary file called
u-boot.dtb. This can be concatenated with the U-Boot binary to provide a
device tree located at run-time by U-Boot. The Makefile is modified to
provide this file in u-boot-dtb.bin.

This new option allows U-Boot to embed a binary device tree into its image
to allow run-time control of peripherals. This device tree is for U-Boot's
own use and is not necessarily the same one as is passed to the kernel.
The device tree compiler output should be placed in the $(obj)
rooted tree. Since $(OBJCOPY) insists on adding the path to the
generated symbol names, to ensure consistency it should be
invoked from the directory where the .dtb file is located and
given the input file name without the path.
This commit contains my entry for the ugliest Makefile / shell interaction
competition.

This adds a device tree pointer to the global data. It can be set by

This is a better name for this protocol. Also remove the typedef to keep
checkpatch happy, and move zeroing of NetBootFileXferSize a little

ICMP packets can tell you when there is no server at the other end. It
is useful for tftp to figure this out, so that a quick error can be
displayed, rather than pointlessly retrying.
This adds an ICMP packet handler to the net interface.

Note: This is kind of guess work. The current code is preserved for

Currently part_efi.c allocates buffers for the gpt_header, the
legacy_mbr, and the pte (partition table entry) that may be
incorrectly aligned for DMA operations.
This patch uses ALLOC_CACHE_ALIGN_BUFFER for the stack allocated
buffers and memalign to replace the malloc of the pte.

Currently the mmc_change_freq and mmc_startup functions allocates
buffers on the stack that are passed down to the MMC device driver.
These buffers could be unaligned to the L1 dcache line size. This
causes problems when using DMA and with caches enabled.
This patch correctly cache alignes the buffers used for reading the
ext_csd data from an MMC device.

Currently, if a device read request is done that does not begin or end
on a sector boundary a stack allocated bounce buffer is used to perform
the read, and then just the part of the sector that is needed is copied
into the users buffer. This stack allocation can mean that the bounce
buffer will not be aligned to the dcache line size. This is a problem
when caches are enabled because unaligned cache invalidates are not
safe.
This patch uses ALLOC_CACHE_ALIGN_BUFFER to create a stack allocated
cache line size aligned bounce buffer.

Commit dc8bbea removed a local variable that is used in most ARM boards.
Since we want to avoid an 'unused variable' warning with later compilers,
and the #ifdef logic of whether this variable is required is bit painful,
this declares the variable local to the block of code that needs it.

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.

net/dns.c used endian conversion macros wrongly (shorts in reply
were put swapped into CPU, and then ntohs() was used to swap it
back, which broke on big-endian).
Fix this by using the correct linux conversion macro for reading
a unaligned short in network byte order: get_unaligned_be16()
Thanks to Mike Frysinger pointing at the best macro to use.
