From a7787b78503a2c67fe02f1fcdd995fb6f3830f4b Mon Sep 17 00:00:00 2001 From: Tang Yuantian Date: Fri, 21 Nov 2014 11:17:15 +0800 Subject: fsl/sleep: updated the deep sleep framework for QorIQ platforms With the introducing of generic board and ARM-based cores, current deep sleep framework doesn't work anymore. This patch will convert the current framework to adapt this change. Basically it does: 1. Converts all the Freescale's DDR driver to support deep sleep. 2. Added basic framework support for ARM-based and PPC-based cores separately.
