ARM is moving to stricter checks on readl/write functions,

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.

        /* set NAND page size to 2k if not configured via boot mode pins */
-       __raw_writel(__raw_readl(MXC_CCM_RCSR) | (1 << 30), MXC_CCM_RCSR);
+       /* FIXME __raw_writel(__raw_readl(MXC_CCM_RCSR) | (1 << 30), MXC_CCM_RCSR); */

Good catch, the correct access would be:
__raw_readl(mx3_ccm_base + MXC_CCM_RCSR) ...

I will fix this after your series reaches linux-next.
