From 159f8cd99ea0e3613cbb6aeea574af438f33d8d7 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Thu, 29 Oct 2009 10:52:06 +0000 Subject: sh: Allow boards to register memory pre/post sleep code Add code to allow boards registering self-contained functions for going to/from self-refresh. At this point the board code is unused. When all supported boards have been converted then the new sleep code will make use of these functions.
