I'm fine using the Rock64 to get things on the
microSD card that I've also been putting in the
RPi4B.

I can even boot the Rock64 via an eMMC and use
the microSD card slot with a microSD card in it
as a separate device, not even requiring USB to
be involved.

I've no RockPro64 access.

Likely my next tests will be of simple booting
of the RPi4B based on head -r357392 (or later).
Then other devices will likely also be updated,
include a couple of SSDs for old PowerMacs (32-bit
and 64-bit).
