+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
+
+Run time view of SPL framework
