T1024 SoC Overview
------------------
The T1024/T1023 dual core and T1014/T1013 single core QorIQ communication processor
combines two or one 64-bit Power Architecture e5500 core respectively with high
performance datapath acceleration logic, and network peripheral bus interfaces
required for networking and telecommunications. This processor can be used in
applications such as enterprise WLAN access points, routers, switches, firewall

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
