"mmc_data8" is not correct, as D6/D7 of the eMMC are not connected to GP6_28
resp. GP6_29, but to GP6_6 resp. GP6_7.
So it should be "mmc_data8_b".

Unfortunately the latter pin group isn't supported by the PFC driver yet.
Cooking a patch...

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
