Attempt to bring i386 / sc520 inline with master

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.

Move determing if we have a ramdisk and where its located into the

ARM, i386, m68k and ppc all have identical implementations of strmhz().
Other architectures don't provide this function at all.

This patch moves strmhz() into lib_generic, reducing code duplication
and providing a more unified API across architectures.

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.

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.

Split the arch-specific logic out of the common go code and into a dedicated
weak function called do_go_exec() that lives in cpu directories.  This will
need review from i386/nios people to make sure I didn't break them.

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.

boot_get_ramdisk() and image_get_ramdisk() do not need all
cmdtp, flag, argc and argv arguments. Simplify routines definition.

Signed-off-by: Marian Balakowicz <m8@semihalf.com>

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.

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.

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

Marian Balakowicz authored 17 years ago and Wolfgang Denk committed 17 years ago

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

Those always evaluated TRUE, and thus were always compiled

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

Based on patch by Mike Frysinger, 20 Jun 2006

Modifications are based on the linux kernel approach and
support two use cases:

  1) Add O= to the make command line
  'make O=/tmp/build all'

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
