Heiko Schocher bbe310922f arm, i.mx27: add support for magnesium board from projectiondesign
This patch adds support for the magnesium board from
projectiondesign. This board uses i.MX27 SoC and has
8MB NOR flash, 128MB NAND flash, FEC ethernet controller
integrated into i.MX27. As this port is based on
the imx27lite port, common config options are collected
in include/configs/imx27lite-common.h
