[PATCH 3.16.y-ckt 090/110] ARM: dts: imx27: only map 4 Kbyte for fec registers

[Luis Henriques]

3.16.7-ckt13 -stable review patch.  If anyone has any objections, please let me know.

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

From: Philippe Reynes <tremyfr at 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.
