From ff6552e4f3505da9c2886098773146be71c872e3 Mon Sep 17 00:00:00 2001 From: Juergen Beisert Date: Sat, 5 Jul 2008 10:03:01 +0200 Subject: [PATCH] i.MX27 family: Add the Phytec PCM970 evaluation board The Phytec phyCORE-i.MX27 CPU module is delivered with the PCM970 baseboard by default. This patch adds support for the hardware. This code is only an empty stub; it is filled up with functionality in a later patch series.
