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.

routines
This patch updates architecture specific implementations of
do_bootm_linux() adding new uImage format handling for
operations like get kernel entry point address, get kernel
image data start address.

Do not pass image verification flag directly to related routines.
Simplify argument passing and move it to the bootm_header structure which
contains curently processed image specific data and is already being passed
on the argument list.

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.

Microblaze do_bootm_linux() includes ramdisk processing code but
the ramdisk does not get used anywhere later on.

Architecture specific do_bootm_linux() routines share common
ramdisk image processing code. Move this code to a common
helper routine.

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
