Summary

Most 64-bit Raspberry Pi models have a variable processor clock
speed that defaults to a slow speed (e.g. 600 MHz for a nominal
1.5 GHz clock). This results in everything running slowly unless
or until powerd is started, and FreeBSD is then thought to be slow.
Enable powerd by default in /etc/rc.conf on the arm64-aarch64-RPI
images. Tested on Raspberry Pi 3B+ and 4B so far.

• karels mentioned this in D43141: Add powerd_enable for RPI4.

There is an alternative approach in https://reviews.freebsd.org/D43141. The main difference is that it splits RPI4 into a separate image, leaving RPI for RPi 3 etc. I don't think that is necessary, as noted in that review. The other difference is in using the quirks mechanism, which would require modification to be effective in this case.
