Hi,
Here is a rough draft to fix the regression. I have only compiled it. I will
update all the boards later.
I have removed the mci_dma_data since it is no more used for ARM platforms.

The thing is, I never saw the prints in my console (i assume that it
prints on the console by default with earlyprintk/debug stuff enabled as

P.S. what I do as a basic test, is on our very very minimal empty debian

Recently I upgraded to Hans's 4.2 tree where he added
