From ce249d956c820af4b9790406461b1748741d0478 Mon Sep 17 00:00:00 2001 From: Tang Yuantian Date: Wed, 23 Jul 2014 17:27:53 +0800 Subject: powerpc/t104xrdb: support deep sleep in SPI/SD boot Add deep sleep support in SPI/SD boot. The destination address second stage uboot image is loaded to is changed because currently this address will be used by kernel which means we can't reserve it for resume. Entry point to kernel is still placed in second stage uboot.
