[U-Boot] [PATCH v2] powerpc/t1040qds: Add support of SD boot for T1040QDS Board
Add support of 2 stage SD boot loader using SPL framework. here, PBL initialise the internal SRAM and copy SPL(160KB). This further initialise DDR using SPD environment and copy u-boot(768 KB) from NAND to DDR. Finally SPL transer control to u-boot.
