From 1dfe34ae794c13b11192baac022826f9c53fe377 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Wed, 29 Feb 2012 10:56:15 -0600 Subject: [PATCH] ARM: iop13xx: use runtime ioremap hook Convert iop13xx platforms to use run-time ioremap hook instead of the compile time hook. The custom ioremap is still needed for 64-bit address handling.
