From f49b8c1b5d9db6d349000b25312c672a1f6627b8 Mon Sep 17 00:00:00 2001 From: tang yuantian Date: Wed, 17 Dec 2014 15:42:54 +0800 Subject: [PATCH] mpc85xx/t102xrdb: convert deep sleep to generic board interface A new deep sleep interface is introduced to support generic board structure. Converts it to use new interface. Besides, added SPI/SD/NAND boot deep sleep support.
