Can you confirm that Jason is the maintainer of the board ?

I have not an evident comment with this code, but there are pending
patches to change this behavior:
http://patchwork.ozlabs.org/patch/132398/
The patches already updates other i.MX boards. If, as I presume, this
patches goes soon in mainline, board_mmc_getcd() must be updated to be
adjusted for the new API. I will wait a while before merging your patch
to check the status of the mmc patchset.

Ok, fine. For my information only, is there a revision version to be
checked if the board needs this small loader ?
