yo. I wrote a patch a while ago at
https://raw.githubusercontent.com/echoline/9emmc/master/9emmc.patch
this was for the eMMC chips in the CM3+ to work (at all)
it does need more changes still... other machine architectures... it
does not take buswidth (happy halloween!!!) into account, I wrote a
lot of it just from looking at the linux kernel, etc...
be safe out there!
love,
uppity 9fans
