I had wondered the same, but expected I'd not understand. Looking just
now, it sounds like it doesn't mix with the NAND variant (-n8G) well?

It looks like the emmc DT has gotten slightly slimmer since being
introduced. It doesn't seem the eMMC DT turns off any part of the NAND
DT, so I might try to poke at this some. But I don't have a NAND
version of the board to fully test.

Oh, right, the tooling would know the proper order. I just sorted it,
but I forgot I had wondered earlier how things were ordered. Thanks
for the explanation.

Thanks for fixing it up.
