Subject: [@num@/@total@] i.MX27: Adding PCM038 platform support From: Juergen Beisert This patch adds support for the phyCORE-i.MX27 cpu module (aka pcm038). Its as generic as possible to support any kind of baseboard. Note: This CPU module implementation can't work without a baseboard support. Baseboard support can be added by the PCM-970 or any custom variant. TODO: - how to avoid duplicate code for GPIO setup? - how to avoid this ugly function to determine external clock (board_get_ckih_rate)?
