DRAM init is quite simple on the I.MX6. Also it is quite simple to
turn on all peripheral
clocks. The IOMUX stuff could be a little bit challenging as I don't
know the current
sw architecture coreboot uses on ARM.

Looks like a fun project for some rainy holiday days :) Maybe I can
help out a little bit as
I did a u-boot board-bring-up for a custom I-MX6D/Q board the last weeks.
