From 6c7e072b1682eeb7c17ed5fdec0672fcf3ccb205 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 14 Jan 2008 10:29:35 -0600 Subject: [PATCH] [POWERPC] fsl_soc: Fix get_immrbase() to use ranges, rather than reg. Don't depend on the reg property as a way to determine the base of the immr space. The reg property might be defined differently for different SoC families.
