This patch adds SD boot support for T4240RDB board. SPL
framework is used. PBL initializes the internal RAM and
copies SPL to it. Then SPL initializes DDR using SPD and
copies u-boot from SD card to DDR, finally SPL transfers
control to u-boot.

Add support of 2-stage NAND/SPI/SD boot loader using SPL framework.
PBL initializes the internal CPC-SRAM and copy SPL(160K) to it,
SPL further initializes DDR using SPD and environment and copy
u-boot(768K) from SPI/SD/NAND to DDR, finally SPL transfers control
to u-boot.

Add support of 2 stage NAND, SD, SPI boot loader using SPL framework.
here, PBL initialise the internal SRAM and copy SPL(160KB). This further
initialise DDR using SPD and 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
