Support for the new spl structure. Using the interface defined by Aneesh V for OMAP4 Signed-off-by: Simon Schwarz <simonschwarzcor@gmail.com> --- V1 changes: ADD support for early console output in SPL V2 changes: ADD include omap_common.h in board.c ADD implement new omap common interface omap_boot_device, omap_boot_mode and omap_rev_string (very basic) CHG cosmetic CHG Don't add ecc switch command in SPL ADD save_boot_params stump with warning to implement it V3 changes: none V4 changes: CHG cosmetic - corrected style problem Transition from V1 to V2 also includes that this patch is now based on - the new SPL layout by Aneesh V and Daniel Schwierzeck - the OMAP4 SPL patches by Aneesh V This is in some parts a anccesstor of "[U-Boot,2/5] devkit8000 nand_spl: omap3 support nand_spl boot" (http://article.gmane.org/gmane.comp.boot-loaders.u-boot/102114) in V1 --- arch/arm/cpu/armv7/omap3/board.c | 37 +++++++++++++++++++++++++- arch/arm/cpu/armv7/omap3/lowlevel_init.S | 5 +++ arch/arm/include/asm/arch-omap3/sys_proto.h | 1 + 3 files changed, 41 insertions(+), 2 deletions(-)
