Subject: [PATCH 04/15] ARM: imx: convert to common runtime ioremap hook

From: [email-masked] (Rob Herring)
Date: Mon, 13 Feb 2012 15:43:17 -0600

From: Rob Herring <[email-masked]>

Convert i.MX platforms to use the common run-time ioremap hook instead of
the imx specific hook.

Also, move addr_in_module out of io.h.
