Andrew,
Thomas did a board conversion here (slated for v3.11 in /pcie branch):
cd2bde5 arm: kirkwood: convert db-88f6281 to the Device Tree
And Sebastian did some mvsdio WP and CD pin work here:
0d0644eARM: Kirkwood: fix unused mvsdio gpio pins
Nothing else really jumps out though. Where either of these what you
were thinking of?
thx,
Jason.
