Subject: [PATCH] imx27: dt: only map 1 Kbyte for fec registers
Date: Sat, 9 May 2015 22:54:30 +0200 [thread overview]
Message-ID: <1431204870-17233-1-git-send-email-tremyfr@gmail.com> (raw)
According to the imx27 documentation, fec has a 1 Kbyte
memory space map, spitted in two regions of 512 bytes.
The first one for control/status registers, and the
second one for event/statistic registers. So, we don't
need to map 16 Kbyte for registers, 1 Kbyte is enough.
