am335x: fix GPMC config for NAND and NOR SPL boot
GPMC controller is common IP to interface with both NAND and NOR flash devices. Also, it supports max 8 chip-selects, which can be independently connected to any of the devices. But ROM code expects the boot-device to be connected to only chip-select[0]. Thus to resolve conflict between NOR 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. Signed-off-by: Pekon Gupta <pekon@ti.com>
