As long as it is reporting:

"APs not started"

that APs issue likely has nothing to do with lack of
rescanning for "card insertion / removal detection".

Also, the examples of

QUOTE

psci0: PSCI version number mismatched with DT
device_attach: psci0 attach returned 6
END QUOTE

are new compared to -r356426 .

There seem to be other, bigger issues not involving
"card insertion / removal detection" at all. I'd
prefer that those be addressed first and do not
plan on looking into rescanning related chnagess at
this time.

"PSCI version number mismatched with DT" and "APs not started"
can not be fixed by such a activity.

I do not get such and I want the APs to start and such.
