d985c8498c [new uImage] Remove unnecessary arguments passed to ramdisk routines
boot_get_ramdisk() and image_get_ramdisk() do not need all
cmdtp, flag, argc and argv arguments. Simplify routines definition.

9a4daad0a3 [new uImage] Update naming convention for bootm/uImage related code
This patch introduces the following prefix convention for the
image format handling and bootm related code:

genimg_		- dual format shared code
image_		- legacy uImage format specific code
fit_		- new uImage format specific code
boot_		- booting process related code

Related routines are renamed and a few pieces of code are moved around and
re-grouped.

d3f2fa0d27 [new uImage] Provide ability to restrict region used for boot images
Allow the user to set 'bootm_low' and 'bootm_size' env vars as a way
to restrict what memory range is used for bootm.

e822d7fc4d [new uImage] Use lmb for bootm allocations
Convert generic ramdisk_high(), get_boot_cmdline(), get_boot_kbd()
functions over to using lmb for allocation of the ramdisk, command line
and kernel bd info.

Convert PPC specific fdt_relocate() to use lmb for allocation of the device
tree.

Provided a weak function that board code can call to do additional
lmb reserves if needed.

Also introduce the concept of bootmap_base to specify the offset in
physical memory that the bootmap is located at.  This is used for
allocations of the cmdline, kernel bd, and device tree as they should
be contained within bootmap_base and bootmap_base + CFG_BOOTMAPSZ.

274cea2bdd [new uImage] rework error handling so common functions don't reset
Changed image_get_ramdisk() to just return NULL on error and have
get_ramdisk() propogate that error to the caller.  It's left to the
caller to call do_reset() if it wants to.

Also moved calling do_reset() in get_fdt() and fdt_relocate() on ppc
to a common location.  In the future we will change get_fdt() and
fdt_relocate() to return success/failure and not call do_reset() at all.

a6612bdfe7 [new uImage] Don't pass kdb to ramdisk_high since we may not have one
We don't actually need the kdb param as we are just using it to get
bd->bi_memsize which we can get from gd->bd->bi_memsize.  Also, if we
boot via OF we might not actually fill out a kdb.

8a5ea3e616 [new uImage] Move image verify flag to bootm_headers structure
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.

d5934ad775 [new uImage] Add dual format uImage support framework
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.

b6b0fe6460 [new uImage] Cleanup do_botm_linux() boot allocations
This patch moves common pre-boot allocation steps shared between PPC
and M68K to a helper routines:

common:
- get_boot_sp_limit()
- get_boot_cmline()
- get_boot_kbd()

platform:
- set_clocks_in_mhz()

ceaed2b1e5 [new uImage] Move ramdisk loading to a common routine
Ramdisk loading code, including initrd_high variable handling,
was duplicated for PPC and M68K platforms. This patch creates
common helper routine that is being called from both platform
do_bootm_linux() routines.

4a995edec1 [new uImage] Rename architecture specific bootm code files
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
