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.

Initialise/create followings required for SPL framework - Add spl.c which defines board_init_f, board_init_r - Update tlb and ddr accordingly

Add T1040QDS_SDCARD_defconfig Update t1040_pbi.cfg to support errata A-007662, A-008007 and LAW for CPC1

Signed-off-by: Vijay Rai vijay.rai@freescale.com --- changes from v1: -Updated Kconfig to support SPL option for T1040QDS
