It's not in mainline 'tho so it can always come out :)

The board we measured this on is based on the mx6slevk and this
particular part of the board (layout, etc) is unchanged.  Micron put the

don't issue a reset before configuring CS1, I still might try and push
that change up for the EVK at least, not armadillo tho).
