2009-03-20lib_*/board.c: do not initialize bi_enet*addr in global dataMike Frysinger
Since everyone is using the environment for mac address storage, there is no point in seeding the global data. The arches that are converted here: i386 m68k microblaze mips nios nios2 sh sparc Signed-off-by: Mike Frysinger <vapier@gentoo.org> CC: Ben Warren <biggerbadderben@gmail.com> CC: Daniel Hellstrom <daniel@gaisler.com> CC: Michal Simek <monstr@seznam.cz> CC: Shinya Kuribayashi <skuribay@ruby.dti.ne.jp> CC: Scott McNutt <smcnutt@psyent.com> CC: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
2009-02-21Cleanup the comment for m68k linux boot argument passing.Richard Retanubun
This patch clarifies the way m68k passes linux boot argument. The one gotcha here is that the assembly instruction that the compiler uses to jump to the kernel is 'jsr' which pushes the program counter for the instruction after the jsr into the stack pointer.

2008-10-29bootm: Add subcommandsKumar Gala
Add the ability to break the steps of the bootm command into several subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go. This allows us to do things like manipulate device trees before they are passed to a booting kernel or setup memory for a secondary core in multicore situations. Not all OS types support all subcommands (currently only start, loados, ramdisk, fdt, and go are supported). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-10-18Added arch_lmb_reserve to allow arch specific memory regions protectionKumar Gala
Each architecture has different ways of determine what regions of memory might not be valid to get overwritten when we boot. This provides a hook to allow them to reserve any regions they care about. Currently only ppc, m68k and sparc need/use this. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-08-26bootm: refactor do_reset and os boot function argsKumar Gala
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.

2008-08-26bootm: move lmb into the bootm_headers_t structureKumar Gala
To allow for persistent state between future bootm subcommands we need the lmb to exist in a global state. Moving it into the bootm_headers_t allows us to do that. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-08-21Consolidate strmhz() implementationHaavard Skinnemoen

2008-04-17Restore the ability to continue booting after legacy image overwriteMarian Balakowicz
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.

2008-02-29[new uImage] Update naming convention for bootm/uImage related codeMarian Balakowicz
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.

2008-02-29[new uImage] Use lmb for bootm allocationsKumar Gala
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. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-02-29[new uImage] rework error handling so common functions don't resetKumar Gala
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.

2008-02-29[new uImage] Don't pass kdb to ramdisk_high since we may not have oneKumar Gala
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>
2008-02-27[new uImage] Move image verify flag to bootm_headers structureMarian Balakowicz

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>
2008-02-07[new uImage] Cleanup do_botm_linux() boot allocationsMarian Balakowicz

2008-02-07[new uImage] Move ramdisk loading to a common routineMarian Balakowicz

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>
