We are using some low-level functions passing chain of skbuff to the
device using CMD53 with scatterlist. If I recall correctly Marvell made
an attempt to have a similar function for it in the mmc stack. Not sure
if that ever made it in. If so I can rework our driver using that API.
If not, I can make a new attempt.
