2008-10-28bootm: 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>

2008-08-26bootm: 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: refactor ramdisk locating codeKumar Gala
Move determing if we have a ramdisk and where its located into the common code. Keep track of the ramdisk start and end in the bootm_headers_t image struct. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-08-26bootm: refactor entry point codeKumar Gala
Move entry point code out of each arch and into common code. Keep the entry point in the bootm_headers_t images struct. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-08-11Fix fallout from autostart revertKumar Gala
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. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-05-27avr32: Put memset in its own sectionHaavard Skinnemoen
All C code is compiled with -ffunction-sections -fdata-sections. Assembly functions should get their own sections as well so that everything looks consistent. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
2008-04-18Restore 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.

2008-03-12[new uImage] Add new uImage format support to arch specific do_bootm_linux() ↵Marian Balakowicz
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>
2008-03-12[new uImage] Remove unnecessary arguments passed to ramdisk routinesMarian Balakowicz
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>
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.

2008-02-27[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.

2008-02-25[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] 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] 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>
2008-02-07[new uImage] Cleanup image header pointer use in bootm codeMarian Balakowicz

2008-01-18AVR32: Initialize ipaddr, loadaddr and bootfile at startupHaavard Skinnemoen

2007-12-17AVR32: Fix logic inversion in disable_interrupts()Haavard Skinnemoen

2007-12-17AVR32: Enable interrupts at bootupHaavard Skinnemoen
The timer code depends on the timer interrupt to keep track of the upper 32 bits of the cycle counter. This obviously doesn't work when interrupts are disabled the whole time. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-10-06AVR32: Initialize bi_flash* in board_init_rHaavard Skinnemoen
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. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-08-10Move 64bit division from avr32 to generic libDirk Behme
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. Signed-off-by: Dirk Behme <dirk.behme@gmail.com>

2007-04-14AVR32: Use initdram() instead of board_init_memories()Haavard Skinnemoen
Conform to the "standard" interface and use initdram() instead of board_init_memories() on AVR32. This enables us to get rid of the sdram_size member of the global_data struct as well. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-14AVR32: Relocate u-boot to SDRAMHaavard Skinnemoen
Relocate the u-boot image into SDRAM like everyone else does. This means that we can handle much larger .data and .bss than we used to. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-04-14AVR32: Resource management rewriteHaavard Skinnemoen
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.

2007-04-14AVR32: Split start_u_boot into board_init_f and board_init_rHaavard Skinnemoen
Split the avr32 initialization code into a function to run before relocation, board_init_f and a function to run after relocation, board_init_r. For now, board_init_f simply calls board_init_r at the end. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
