[PATCH 3.13.y-ckt 09/56] ARM: dts: imx27: only map 4 Kbyte for fec registers
From: Kamal Mostafa
Date: Wed Jul 08 2015 - 11:56:42 EST
3.13.11-ckt23 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Philippe Reynes <tremyfr@xxxxxxxxx>
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.
