From 4d66668300439972abc4990f23fdea771f0830fd Mon Sep 17 00:00:00 2001 From: Shengzhou Liu Date: Fri, 18 Apr 2014 16:43:40 +0800 Subject: board/t208xrdb: Add support of 2-stage NAND/SPI/SD 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.
