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.

I'd say this patch isn't critical enough to be picked up for stable and
I wonder why you consider it. Is this just because it has a Fixed:
footer?

Best regards
Uwe

No.  That's because I added Cc: stable tag when applying.
