From 4cb55ca1dbd992436a090d05d0e1ab17ea749447 Mon Sep 17 00:00:00 2001 From: Omar Ramirez Luna Date: Thu, 10 Jan 2013 03:37:01 -0600 Subject: [PATCH] staging: tidspbridge: use scm functions to set boot address and mode Instead of ioremapping SCM registers, use the correspondent layer to write into them. This allows us to get rid of a layer violation, since the registers are no longer touched by driver code.
