From ef8397cfb3a385bc57a32213d0e4a5b7903a9dc6 Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Sat, 13 Nov 2010 19:11:22 +0100 Subject: [PATCH] rt2x00: Use ioremap for SoC devices instead of KSEG1ADDR. Make the code a bit more portable to architectures that do not support KSEG1ADDR. Signed-off-by: Gertjan van Wingerde Tested-by: Helmut Schaa Signed-off-by: Ivo van Doorn Signed-off-by: John W.
