2-stage NAND/SPI/SD boot loader
-------------------------------
PBL initializes the internal CPC-SRAM and copy SPL(160K) to SRAM.
SPL further initializes DDR using SPD and environment variables
and copy u-boot(768 KB) from NAND/SPI/SD device to DDR.
Finally SPL transers control to u-boot for futher booting.

SPL has following features:
 - Executes within 256K
 - No relocation required
