[U-Boot] [PATCH 1/2] board/t208xqds: Add support of 2-stage NAND bootloader
Shengzhou Liu
Shengzhou.Liu at freescale.com
Fri Mar 14 09:15:12 CET 2014
Add support of 2 stage NAND boot loader using SPL framework.
PBL initialise the internal SRAM and copy SPL(96K), this further
initialise DDR using SPD and environment and copy u-boot from NAND
to DDR, finally SPL transfer control to u-boot.
