2008-02-27[new uImage] Correct raw FDT blob handlig when CONFIG_FIT is disabledMarian Balakowicz
Dual format image code must properly handle all three FDT passing methods: - raw FDT blob passed - FDT blob embedded in the legacy uImage - FDT blob embedded in the new uImage This patch enables proper raw FDT handling when no FIT imaeg support is compiled in. This is a bit tricky as we must dected FIT format even when FIT uImage handling is not enabled as both FIT uImages and raw FDT blobs use tha same low level format (libfdt).

2008-02-27[new uImage] POWERPC: Add image_get_fdt() routineMarian Balakowicz
FDT blob may be passed either: (1) raw (2) or embedded in the legacy uImage (3) or embedded in the new uImage. For the (2) case embedding image must be verified before we get FDT from it. This patch factors out legacy image specific verification routine to the separate helper routine. Signed-off-by: Marian Balakowicz <m8@semihalf.com> Acked-by: Kumar Gala <galak@kernel.crashing.org>
2008-02-27[new uImage] Move image verify flag to bootm_headers structureMarian Balakowicz
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.

2008-02-27[new uImage] POWERPC: Split get_fdt() into get and relocate routinesMarian Balakowicz
PPC specific FDT blob handling code is divided into two separate routines: get_fdt() - find and verify a FDT blob (either raw or image embedded) fdt_relocate() - move FDT blob to within BOOTMAP if needed Signed-off-by: Marian Balakowicz <m8@semihalf.com> Acked-by: Kumar Gala <galak@kernel.crashing.org>
2008-02-25[new uImage] Add dual format uImage support frameworkMarian Balakowicz
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. Signed-off-by: Marian Balakowicz <m8@semihalf.com>
2008-02-21[new uImage] Rename and move print_image_hdr() routineMarian Balakowicz
Signed-off-by: Marian Balakowicz <m8@semihalf.com>
2008-02-21[new uImage] Add gen_get_image() routineMarian Balakowicz
This routine assures that image (whether legacy or FIT) is not in a special dataflash storage. If image address is a dataflash address image is moved to system RAM. Signed-off-by: Marian Balakowicz <m8@semihalf.com>
2008-02-07[new uImage] Cleanup FDT handling in PPC do_boot_linux()Marian Balakowicz
Move FDT blob finding and relocation to a dedicated get_fdt() routine. It increases code readability and will make adding support for new uImage format easier. Signed-off-by: Marian Balakowicz <m8@semihalf.com>
2008-02-07[new uImage] Cleanup do_botm_linux() boot allocationsMarian Balakowicz
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() Signed-off-by: Marian Balakowicz <m8@semihalf.com>
2008-02-07[new uImage] Move ramdisk loading to a common routineMarian Balakowicz
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. Signed-off-by: Marian Balakowicz <m8@semihalf.com>
2008-02-07[new uImage] Factor out common image_get_ramdisk() routineMarian Balakowicz
Architecture specific do_bootm_linux() routines share common ramdisk image processing code. Move this code to a common helper routine. Signed-off-by: Marian Balakowicz <m8@semihalf.com>
2008-02-07[new uImage] Move FDT error printing to common fdt_error() routineMarian Balakowicz
FDT error handling in PPC do_bootm_linux() shares the same message format. This patch moves error message printing to a helper fdt_error() routine. Signed-off-by: Marian Balakowicz <m8@semihalf.com> Acked-by: Gerald Van Baren <vanbaren@cideas.com>
2008-02-07[new uImage] Remove OF_FLAT_TREE support from PPC bootm codeMarian Balakowicz
Support for OF_FLAT_TREE is to be obsoleted in the near future, remove related code from the bootm routines. Signed-off-by: Marian Balakowicz <m8@semihalf.com>
2008-02-07[new uImage] Rename architecture specific bootm code filesMarian Balakowicz
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 Signed-off-by: Marian Balakowicz <m8@semihalf.com>
