 This is fixed in head and stable/13 :
https://cgit.freebsd.org/src/commit/?id=1cf282363101f5d99b1dadfb0d3250bbe6f482a5
https://cgit.freebsd.org/src/commit/?id=2551d928501fb613dba09b7ffe7e383dba276ca6

 I'm waiting on re@ approval for 13.0

 Note that you will also need two files provides in an issue on
rpi-firmware github, see
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252971#c25 for more
info.
 I'm waiting for rpi foundation to release a new version of the
firmware file and will commit an update to the port.
 I hope that they release that early next week to 13.0-RC1 can have
them.

 Cheers,
