2008-12-07SPARC: Fixed compiler error introduced by commit c160a9544743Daniel Hellstrom
This patch fixes a build error for the SPARC platform. It was introduced by commit c160a9544743e80e8889edb2275538e7764ce334. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com>
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: refactor image detection and os load stepsKumar Gala
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>
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>
2008-08-26bootm: 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>
2008-08-12Fix 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>
