Knowing the booting source of the part is useful, especially when the part
can switch dynamically between sources.

Rather than using 8bit transfers for everything, use 8/16/32 bit transfers
as usable with the source/destination addresses and the count size.

We have to make sure the DMA channel is actually disabled in hardware before
attempting to reprogram it. Otherwise the new settings are ignored and we
end up with random hangs/failures.

Take the cache flush functions from the kernel as they use hardware loops in

Calculating the clocks requires a bit of calls to gcc math functions, so
cache the values after the first run since they'll most likely never
change once U-Boot is up and running.

Make sure we save the value of RETX at power on and then pass it on to the
kernel so that it can nicely debug a "double-fault-caused-a-reset" crash.

Respect the CONFIG_SYS_MONITOR_LEN define rather than assuming a size of

Our dcache invalidate function doesn't just invalidate, it also flushes.
So rename the function accordingly and fix the dma_memcpy() function so it
doesn't inadvertently corrupt the data destination.

Creating a new dma_memcpy() function that skips all cache checks allows us
to use the function in very early init where the cache is not yet setup.

Add the ability to break the steps of the bootm command into several
subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go.
This allows us to do things like manipulate device trees before
they are passed to a booting kernel or setup memory for a secondary
core in multicore situations.
Not all OS types support all subcommands (currently only start, loados,
ramdisk, fdt, and go are supported).

If booting out of NAND, we need to make sure we initialize it properly

There is no need for each OS specific function to call do_reset() we
can just do it once in bootm. This means its feasible on an error for
the OS boot function to return.
Also, remove passing in cmd_tbl_t as its not needed by the OS boot
functions. flag isn't currently used but might be in the future so
we left it alone.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

Before new uImage code was merged, bootm code allowed for the kernel image to
get overwritten during decompresion. new uImage introduced a check for image
overwrites and refused to boot the image that got overwritten. This patch
restores the old behavior. It also adds a warning when the image overwriten is
a multi-image file, because in such case accessing componentes other than the
first one will fail.

This patch adds framework for dual format images. Format detection is added
and the bootm controll flow is updated to include cases for new FIT format
uImages.
When the legacy (image_header based) format is detected appropriate
legacy specific handling is invoked. For the new (FIT based) format uImages
dual boot framework has a minial support, that will only print out a
corresponding debug messages. Implementation of the FIT specific handling will
be added in following patches.

Implementation of the do_bootm_linux() and other bootm helper routines is
architecture specific code. As such it resides in lib_<arch> directories
in files named <arch>_linux.c
This patch renames those files to a more clear and accurate
lib_<arch>/bootm.c form.
List of the renamed files:
lib_arm/armlinux.c -> lib_arm/bootm.c
lib_avr32/avr32_linux.c -> lib_avr32/bootm.c
lib_blackfin/bf533_linux.c -> lib_blackfin/bootm.c
lib_i386/i386_linux.c -> lib_i386/bootm.c
lib_m68k/m68k_linux.c -> lib_m68k/bootm.c
lib_microblaze/microblaze_linux.c -> lib_microblaze/bootm.c
lib_mips/mips_linux.c -> lib_mips/bootm.c
lib_nios/nios_linux.c -> lib_nios/bootm.c
lib_nios2/nios_linux.c -> lib_nios2/bootm.c
lib_ppc/ppc_linux.c -> lib_ppc/bootm.c
lib_sh/sh_linux.c -> lib_sh/bootm.c
