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. Signed-off-by: Juergen Beisert <j.beisert@pengutronix.de>
