Thanks, I tried booting NetBSD-current from today on RPi4 4 GiB, but kernel hangs half way through the boot. Last message printed "WARNING: extracting entropy too early".
This is the same problem I reported, which is apparently due to the way that RPI_EFI.fd is written, I'm guessing.
If you'd like to try the copy from Paul (shared with permission) which has the preference of limiting to 3 gigs disabled, then you can get it here:
