updates BCH8_ECC schemes in mtd/nand/omap_gpmc.c driver
- adds scalability for higher ECC schemes in future.
- removes CONFIG_AM335x and it makes it generic for all platforms.
- optimizes read_data paths
Pekon Gupta (4):
mtd: nand: omap: make am33xx/elm.c as common driver for all OMAPx
and NAND boot. This patch:
- combines NOR and NAND configs spread in board files to common gpmc_init()
- configures GPMC based on boot-mode selected for SPL boot.
