    Subject[PATCH 3.13.y-ckt 09/56] ARM: dts: imx27: only map 4 Kbyte for fec registers
    Date
    3.13.11-ckt23 -stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Philippe Reynes <tremyfr@gmail.com>

    commit a29ef819f3f34f89a1b9b6a939b4c1cdfe1e85ce upstream.

    According to the imx27 documentation, fec has a 4 Kbyte
    memory space map. Moreover, the actual 16 Kbyte mapping
    overlaps the SCC (Security Controller) memory register
    space. So, we reduce the memory register space to 4 Kbyte.
