Marius is currently updating our mmc/sd stack for better support of
modern emmc, there's a good chance that support will hit 11-stable in a

There is also work in progress on sdio, but that's still focused on the
lower level support.  Once that infrastructure is in place, another
round of work will be needed to create the wifi drivers.
