Please do when you have time.

I haven't see any SD card issues using the current code with light usage
 / testing, however it's possible I'm just getting lucky.  It would be
useful to hear from other people.

I'm aware that the eMMC support needs additional work and will get back
to it.  I'm currently looking at porting the NetBSD dwc_gmac driver since
it's known to work for the Amlogic DWC ethernet controller (as well as
the Allwinner).
