This series includes independent patch-sets aiming to enable x16 NAND support on AM33xx boards (like beaglebone-LT). [PATCH 1/4]: This patch is ported from linux driver/mtd/nand to allow detection device-width of NAND by reading ONFI parameter page. [PATCH 2/4]: enable NAND_BUSWIDTH_AUTO feature in omap_nand.c [PATCH 3/4]: cleaning of GPMC configs for NAND and NOR [PATCH 4/4]: enable x16 and x8 NAND device pin-muxing for beagle-bone LT (white)
However, this patch does not enable NAND boot via x16 device, as SPL boot does not have capability of reading on-chip ONFI parameters so x16 device would not get detected in SPL NAND boot. Thus x16 device would be detected only once second-stage of u-boot is loaded via some other boot-source like SD/MMC.
