3216ca9692 Fix fallout from autostart revert
The autostart revert caused a bit of duplicated code as well as
code that was using images->autostart that needs to get removed so
we can build again.

cb1c489690 Restore the ability to continue booting after legacy image overwrite
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.

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.

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.

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
