As discussed in the ML, this patchset does not make SPL common to all SOCs to avoid breaking some architecture - this job will be done later with a different patchset.

[U-Boot] SPL Linux Boot
Hi, this is a new submission of the Simon's work to add a way to boot Linux directly from the SPL. From the last patchset series, the main changes introduced by me are the following: - compile the cache functions in SPL to make cleanup_before_linux() available. - do not call IC function on boards where I2C is not available - fix a bug from last version (fallback to U-Boot) - move all related SPL stuff to common/ and fix omap related functions. Tested on the twister board (patches for this board in u-boot-ti, next) Note: to test it is also required Simon's patch: arm: Add Prep subcommand support to bootm http://patchwork.ozlabs.org/patch/129753/ [PATCH V11 01/13] Add cmd_spl command [PATCH V11 02/13] devki8000: add config for spl command [PATCH V11 03/13] omap-common: Add NAND SPL linux booting [PATCH V11 04/13] devkit8000/spl: init GPMC for dm9000 in SPL [PATCH V11 05/13] omap-common/spl: Add linux boot to SPL [PATCH V11 06/13] omap/spl: change output of spl_parse_image_header [PATCH V11 07/13] devkit8000: Implement and activate direct OS boot [PATCH V11 08/13] Add cache functions to SPL for armv7 [PATCH V11 09/13] OMAP3: SPL: do not call I2C init if no I2C is [PATCH V11 10/13] OMAP3: move SPL files to be used by other [PATCH V11 11/13] TI: SPL: make SPL available for other SOCs as TI [PATCH V11 12/13] SPL: call cleanup_before_linux() before booting [PATCH V11 13/13] OMAP3: twister: add support to boot Linux from ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

I'll do, I have not yet tested and I built OMAP3. I have seen a couple of other things due to the moved stuff that I should fix. omap4/5 has smaller size requirements than omap3(ish) stuff and I don't have 100% faith in linker magic to make sure the cache stuff added to SPL in arch/arm/lib/ isn't going to bloat up the omap4/5 stuff slightly. Ok, understood, I'll check it - if the added code is too much, I will introduce a new CONFIG_SPL_SUPPORT_CACHE to make build optional.
