[U-Boot] [PATCH v1 5/7] board/ti/am335x: update configs for parallel NAND

Pekon Gupta
2014-07-04T19:05:15Z

This patch
- consolidate CONFIG_SYS_NAND_xx and CONFIG_SPL_NAND_xx from various
configuration files into single file.
- update MTD Partition table to match AM335x_EVM DT in linux-kernel
- segregate CONFIGs based on different boot modes (like SPL and U-Boot)
