[U-Boot] [PATCH v4 19/20] SPL: NAND: Enhance drivers/mtd/nand/nand_spl_simple.c

Tom Rini
2012-08-24T23:58:33Z

Takes the load function from arch/arm/cpu/armv7/omap-common/spl_nand.c
instead. This will allow for easier integration of SPL-boots-Linux code on
other arches.

Signed-off-by: Tom Rini <trini@ti.com>

Changes in v4:
- Leave nand_spl_load.c alone, move the new load into nand_spl_simple.c
