I got my hands on a AM18x WL12xx module so I could test MMC1 and this exposed some bugs in the driver's handling of the second EDMA controller case. DA850/OMAP-L138/AM1x have this second EDMA controller. I've addressed this in v2 which will be posted shortly. I'm expecting to receive a DM646x EVM RSN so I can cover testing that part as well. -Matt
