Hi,
on some GPD Pocket mlarkin@ has the eMMC doesn't come up. One issue
is that we shouldn't go to 0V on some/most(?) Intel controllers. This
only adds it for his machine, but I know that the Appollo Lake versions
might also work if added to this check. But unless verified I'll not
add it. This makes mlarkin@'s machine work, even though it's utterly
slow. That would be the next thing to fix... probably low clocks or
doesn't use 8-bit.
ok?
Patrick
