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.

Currently the sd_change_freq function allocates two buffers on the
stack that it passes 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
scr register and switch status values from an MMC device.

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.
Tested on big and little endian qemu boards (mips and versatile)

ARCH_DMA_MINALIGN will be used to allocate DMA buffers that are
aligned correctly. In all current cases this means that the DMA
buffer will be aligned to at least the L1 data cache line size of
the configured architecture. If the board configuration file
does not specify the architecture L1 data cache line size then the
maximum line size of the architecture is used to align DMA buffers.

The current autoconf.mk.dep rule uses the host cflags when executing the
target compiler (which includes target header files). We don't want to
mix the target compiler and host compiler flags, so change it to CFLAGS.
Otherwise we get things like -pedantic which the U-Boot source code does
not build with.
