[PATCH] Phytec phyFLEX i.MX6 support

[Sascha Hauer]

This adds Phytec phyFLEX i.MX6 board support and some preliminary patches
to support multiple SDRAM settings per board. Also The FEC address can
now be registered from the i.MX6 OCOTP.

[PATCH 1/6] scripts: imx-image: allow semicolon as command delimiter

[Sascha Hauer]

When we want to pass the imxcfg files through cpp we also want to
allow defines which define multiple commands. For this to work we
have to use an additional command delimiter as we can't pass '\n'
though cpp. Use ';' for this.

[PATCH 6/6] ARM: Add Phytec phyFLEX-i.MX6 board support

[Sascha Hauer]

This adds support for the Phytec phyFLEX-i.MX6 board. The phyFLEX-i.MX6
is a system-on-module based on the Freescale i.MX6 SoC. This patch supports
the 1GiB and 2GiB variants on a PBA-B-01 baseboard.
