Marek,

This is great - this would be a great addition to U-Boot IMX6 SPL.

You must have forgotten to post a dependent patch that adds some of
the registers to mmdc_p_regs. If you can post that I can run this
through some testing. Also, in a follow-on post we should add some
more verbiage about how long this takes to perform (I believe you told
me ~10ms) and where to refer in the IMX6 RM's for the steps followed.

Regards,

Tim
