I'll repost then without the quirk.

In fact just this morning - I was about to update -  I was able to test
on an early board revision with a different eMMC module (at the time
RPMB wasnt validated) which upon reflashing also exhibited the issue

see below:

# cat /sys/class/mmc_host/mmc0/mmc0\:0001/csd

# cat /sys/class/mmc_host/mmc0/mmc0\:0001/name
