* AVR32: Must add NOPs after disabling interrupts for AT32UC3A0512ESOlav Morken2009-02-23-0/+7
| | | | | | | | | | The AT32UC3A0512ES chip has a bug when disabling interrupts. As a workaround, two NOPs can be inserted.

* AVR32: Move addrspace.h to arch-directory, and move some functions from io.h ↵Olav Morken2009-02-23-1/+1
| | | | | | | | | | | | | | | to addrspace.h The AVR32A architecture (which AT32UC3A-series is based on) has a different memory layout than the AVR32B-architecture. This patch moves addrspace.h to an arch-dependent directory in preparation for AT32UC3A-support. It also moves some address-space manipulation functions from io.h to addrspace.h.

* AVR32: Make cacheflush cpu-dependentOlav Morken2009-02-23-1/+1
| | | | | | | | | | | The AT32UC3A series of processors doesn't contain any cache, and issuing cache control instructions on those will cause an exception. This commit makes cacheflush.h arch-dependent in preparation for the AT32UC3A-support.

| * bootm: Add subcommandsKumar Gala2008-10-29-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* | avr32: use board_early_init_r instead of board_init_infoHaavard Skinnemoen2008-09-01-1/+3
| | | | | | | | | | | | | | | | | | | | Replace the avr32-specific board_init_info hook by the standard board_early_init_r hook and make it optional. board_early_init_r() runs somewhat earlier than board_init_info used to do, but this isn't a problem for any of the in-tree boards.

* | avr32: Use board_postclk_init instead of gclk_initHaavard Skinnemoen2008-09-01-0/+8
|/ | | | | | | | | | | | | | | | | | Replace the avr32-specific gclk_init() board hook with the standard board_postclk_init() hook which is supposed to run at the same point during initialization. Provide a dummy weak alias for boards not implementing this hook. The cost of this is: - 2 bytes for the dummy function (retal 0) - 2 bytes for each unnecessary function call (short rcall) which is a pretty small price to pay for avoiding lots of #ifdef clutter. In this particular case, all boards probably end up slightly smaller because we avoid the conditional checking if the gclk_init symbol is NULL.

* bootm: refactor do_reset and os boot function argsKumar Gala2008-08-26-8/+2
| | | | | | | | | | | | 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.

* 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.

| | | | | | | | | | | | | | 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] Rename architecture specific bootm code filesMarian Balakowicz2008-02-07-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | 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.
