From a29ef819f3f34f89a1b9b6a939b4c1cdfe1e85ce Mon Sep 17 00:00:00 2001 From: Philippe Reynes Date: Wed, 13 May 2015 00:18:26 +0200 Subject: [PATCH 1/2] ARM: dts: imx27: only map 4 Kbyte for fec registers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
