* bootm: refactor do_reset and os boot function argsKumar Gala2008-08-26-32/+35
| | | | | | | | | | | | 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.

* bootm: refactor image detection and os load stepsKumar Gala2008-08-26-90/+126
| | | | | | | | | | | | | | Created a bootm_start() that handles the parsing and detection of all the images that will be used by the bootm command (OS, ramdisk, fdt). As part of this we now tract all the relevant image offsets in the bootm_headers_t struct. This will allow us to have all the needed state for future sub-commands and lets us reduce a bit of arch specific code on SPARC. Created a bootm_load_os() that deals with decompression and loading the OS image. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: move lmb into the bootm_headers_t structureKumar Gala2008-08-26-7/+4
| | | | | | | | 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>
* bootm: Set working fdt address as part of the bootm flowKumar Gala2008-08-26-0/+8
| | | | | | | | Set the fdt working address so "fdt FOO" commands can be used as part of the bootm flow. Also set an the environment variable "fdtaddr" with the value. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: refactor fdt locating and relocation codeKumar Gala2008-08-26-0/+10
| | | | | | | Move the code that handles finding a device tree blob and relocating it (if needed) into common code so all arch's have access to it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: refactor ramdisk locating codeKumar Gala2008-08-26-0/+38
| | | | | | | | 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>
* bootm: refactor entry point codeKumar Gala2008-08-26-9/+22
| | | | | | | 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>
* Clean up usage of icache_disable/dcache_disableKumar Gala2008-08-19-2/+0
| | | | | | | | | | | | There is no point in disabling the icache on 7xx/74xx/86xx parts and not also flushing the icache. All callers of invalidate_l1_instruction_cache() call icache_disable() right after. Make it so icache_disable() calls invalidate_l1_instruction_cache() for us. Also, dcache_disable() already calls dcache_flush() so there is no point in the explicit calls of dcache_flush(). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Fix fallout from autostart revertKumar Gala2008-08-12-3/+2
| | | | | | | | 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>
* Revert "[new uImage] Add autostart flag to bootm_headers structure"Wolfgang Denk2008-08-10-1/+0
| | | | | | | | | | | | | | | | | This reverts commit f5614e7926863bf0225ec860d9b319741a9c4004. The commit was based on a misunderstanding of the (documented) meaning of the 'autostart' environment variable. It might cause boards to hang if 'autostart' was used, with the potential to brick them. Go back to the documented behaviour.

* USB: shutdown USB before bootingMarkus Klotzbücher2008-07-10-0/+18
| | | | | | | | | | | | | | | | | | This patch fixes a potentially serious issue related to USB which was discouvered by Martin Krause <martin.krause@tqs.de> and fixed for ARM920T. Martin wrote: Turn off USB to prevent the host controller from writing to the SDRAM while Linux is booting. This could happen, because the HCCA (Host Controller Communication Area) lies within the SDRAM and the host controller writes continously to this area (as busmaster!), for example to increase the HccaFrameNumber variable, which happens every 1 ms. This is a slightly modified version of the patch in order to shutdown USB when booting on all architectures. Signed-off-by: Markus Klotzbuecher <mk@denx.de>

* Restore the ability to continue booting after legacy image overwriteMarian Balakowicz2008-04-17-11/+26
| | | | | | | | | | | 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] Use lmb for bootm allocationsKumar Gala2008-02-29-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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] Add autostart flag to bootm_headers structureKumar Gala2008-02-29-0/+1

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