[U-Boot] i.MX needs prior to DM conversion?

Hey guys,

So, from the BLK conversion thread, I'd like to bring up and ask what needs to happen before we can consider the i.MX families ready for bulk conversion to using DM (and OF_CONTROL and BLK and ..) at least in full U-Boot. I know some things have been converted already and some platforms do make use of it, but we have some missing items too. For example, both drivers/mmc/fsl_esdhc.c and drivers/ata/dwc_ahsata.c need conversion. Is anyone able to start on either of these soon? Thanks!
