From 8ab967b6c6007adbd30e58dfa9ef69154a351484 Mon Sep 17 00:00:00 2001 From: Alison Wang Date: Tue, 9 Dec 2014 17:38:14 +0800 Subject: arm: ls102xa: Add NAND boot support for LS1021AQDS board This patch adds NAND boot support for LS1021AQDS board. SPL framework is used. PBL initialize the internal RAM and copy SPL to it, then SPL initialize DDR using SPD and copy u-boot from NAND flash to DDR, finally SPL transfer control to u-boot.
