* Restore the ability to continue booting after legacy image overwriteMarian Balakowicz2008-04-17-1/+1
| | | | | | | | | | | 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.

* [new uImage] Add new uImage format support to arch specific do_bootm_linux() ↵Marian Balakowicz2008-03-12-5/+7
| | | | | | | | | | | 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. Signed-off-by: Marian Balakowicz <m8@semihalf.com>
* [new uImage] Remove unnecessary arguments passed to ramdisk routinesMarian Balakowicz2008-03-12-3/+2
| | | | | | | 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>
* [new uImage] Update naming convention for bootm/uImage related codeMarian Balakowicz2008-02-29-4/+5
| | | | | | | | | | | | | | | 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.

* [new uImage] Provide ability to restrict region used for boot imagesKumar Gala2008-02-29-1/+3
| | | | | | | | Allow the user to set 'bootm_low' and 'bootm_size' env vars as a way to restrict what memory range is used for bootm. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Marian Balakowicz <m8@semihalf.com>
* [new uImage] Use lmb for bootm allocationsKumar Gala2008-02-29-7/+19
| | | | | | | | | | | | | | | | | | | 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.

* [new uImage] rework error handling so common functions don't resetKumar Gala2008-02-29-1/+12
| | | | | | | | | | | | | 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.

* [new uImage] Don't pass kdb to ramdisk_high since we may not have oneKumar Gala2008-02-29-2/+1
| | | | | | | | | 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. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Marian Balakowicz <m8@semihalf.com>
* [new uImage] Move image verify flag to bootm_headers structureMarian Balakowicz2008-02-27-2/+2
| | | | | | | | | | 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.

* [new uImage] Add dual format uImage support frameworkMarian Balakowicz2008-02-25-7/+19
| | | | | | | | | | | | | | 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>
* [new uImage] Cleanup do_botm_linux() boot allocationsMarian Balakowicz2008-02-07-44/+28
| | | | | | | | | | | | | | | 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>
* [new uImage] Move ramdisk loading to a common routineMarian Balakowicz2008-02-07-88/+26
| | | | | | | | | 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>
* [new uImage] Factor out common image_get_ramdisk() routineMarian Balakowicz2008-02-07-80/+9
| | | | | | | | 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>
* [new uImage] Rename architecture specific bootm code filesMarian Balakowicz2008-02-07-0/+279
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>
