From d612f0ab34b27be4ad50b1236fbd6c84450997f1 Mon Sep 17 00:00:00 2001 From: Alison Wang Date: Tue, 9 Dec 2014 17:38:02 +0800 Subject: arm: ls102xa: Add QSPI boot support for LS1021AQDS/TWR board This patch adds QSPI boot support for LS1021AQDS/TWR board. The QSPI boot image need to be programmed into the QSPI flash first. Then the booting will start from QSPI memory space.
