cd7c596e9f [new uImage] Add new uImage format support to arch specific do_bootm_linux() 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.

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

7b624ad254 AVR32: Initialize bi_flash* in board_init_r
The ATSTK1000-specific flash driver intializes bi_flashstart,
bi_flashsize and bi_flashoffset, but other flash drivers, like the CFI
driver, don't.

Initialize these in board_init_r instead so that things will still be
set up correctly when we switch to the CFI driver.

f7c086e94e Move 64bit division from avr32 to generic lib
Move the 64bit division from lib_avr32 to lib_generic. With this, all
boards can do_div/__div64_32 if needed, not only avr one. Code is put
to lib_generic, so no larger memory footprint if not used. No code
modifications. Thanks for proposal by Håvard Skinnemoen.

df548d3c3e AVR32: Resource management rewrite
Rewrite the resource management code (i.e. I/O memory, clock gating,
gpio) so it doesn't depend on any global state. This is necessary
because this code is heavily used before relocation to RAM, so we
can't write to any global variables.

As an added bonus, this makes u-boot's memory footprint a bit smaller,
although some functionality has been left out; all clocks are enabled
all the time, and there's no checking for gpio line conflicts.
