FYI: pkgbase provides multiple main kernels, including non-debug and
debug ones. But the world build it provides is always a debug world,
which is the bigger time taker from what I've seen.

The partial/draft EDK2 does not have fan control of itself: "Supported
peripherals in UEFI" reports: "RP1 PWM Not working Fan control". It
leaves such as the RPi5 firmware sets things up.

Modern enough EEPROM content will mean that the RPI5 firmware no longer
keeps the fan running. (I assume that RPi5 firmware behavior has not
changed again in more recent times.)

Cool.
