Yes, this is a point I raised also on lkml when I submitted the MMC
driver for the Meson8b.
Since the registers mapping is different I assume that this is the
case. Just to be sure, given that you are the only one with a
datasheet for the GXBB, can you confirm that?

Actually for the same reason I was in doubt if CONFIG_MMC_MESON was a
right naming choice here, but since it is really unlikely that we will
ever see a U-Boot port for the Meson8b I stuck with that.

Cheers,
