Subject: [PATCH 05/24] ARM: imx: use __iomem pointers for MMIO
Date: Fri, 14 Sep 2012 23:34:33 +0200	[thread overview]
Message-ID: <1347658492-11608-6-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1347658492-11608-1-git-send-email-arnd@arndb.de>

ARM is moving to stricter checks on readl/write functions,
so we need to use the correct types everywhere.

This found a bug in mach-armadillo5x0.c, where we attempt mmio
on the MXC_CCM_RCSR address that is currently defined to 0xc
and consequently causes an illegal address access.
