Add NAND support for the new SPL structure. Signed-off-by: Simon Schwarz <simonschwarzcor@gmail.com> --- This patch didn't exist before V2! V2 changes: ADD Some define-barriers for OMAP3 to only use NAND ADD nand_load_image() - inits the OMAP gpmc, loads the images - parses the header CHG cosmetic ADD do_reset() implementation for omap-common spl ADD nand_copy_image to nand.h ADD CPP barriers for mmc and nand support. The parts depending on library support are only compiled if the respective library is included. V3 changes: ADD Comment why setup_clocks_for_console() isn't called for OMAP3 CHG cosmetic (deleted empty line) CHG rename of NAND_MODE_HW to NAND_MODE_HW_ECC DEL NAND_MODE_SW. Not used. V4 changes: CHG cosmetic - style problems V5 changes: CHG renamed nand_copy_image to nand_spl_load_image CHG offs paramter of nand_spl_load_image is of type loff_t now V6 changes: ADD call to nand_deselect after loading the images ADD nand_deselect to nand.h V7 changes: DEL some CONFIG_SPL_* relying on garbage collection now ADD mmc_load_image and nand_load_image now have __attribute__((unused)) to prevent warnings when the lib is not added to SPL DEL do_reset() isn't used anymore CHG header based loading in SPL 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 --- arch/arm/cpu/armv7/omap-common/spl.c | 42 +++++++++++++++++++++++++++++++++- arch/arm/include/asm/omap_common.h | 1 + include/nand.h | 3 ++ 3 files changed, 45 insertions(+), 1 deletions(-)
