RPi4 NetBSD 11.0 UEFI firmware v1.52 issues

[Ramiro Aceves <ea1abz%gmail.com@localhost>]

Hello,

Just in case it helps someone using the RPi4 and UEFI github/pftf UEFI firmware.

After my Sandisk SD card breakage I reinstalled NetBSD 11.0 in a spare
SD from  https://cdn.netbsd.org/pub/NetBSD/NetBSD-11.0/evbarm-aarch64/binary/gzimg/arm64.img.gz
image, using a NetBSD amd64 PC and a SD card reader. Mounted the FAT
partition and unpacked github/pftf v1.52 release UEFI firmware over
/boot directory.

After disabling 3 GB RAM limit and changing boot order, I booted
NetBSD. Even network worked and could install several packages, but
soon I started to notice problems. Network stopped working and could
not fix it (using sysinst, both static IP and DHCP). Also noticed that
rebooting the RPi4 was annoying because it stopped at the raspberry
image, before entering the "BIOS", being stuck at that point.
Ctrl+alt+supr restarted it again and could boot NetBSD. That would be
a big problem when doing remote reboots. But it was imposible to fix
the network. That was frustrating.

I recalled my problems in the past  with v1.51 (they made me return
back to v1.50, I posted it here) and I unpacked v1.50 that was working
fine before. Everything was inmediately working normally! Good reboots
and great network connectivity.

I noticed that when using v1.52, I was surfing in the "BIOS" menu
trying to fix the malfunctioning, and I saw that network MAC address
was 00:00:00:00:00:00 but did not take into account at that moment.

Today, I saw this  https://github.com/pftf/RPi4/issues/283 report that
showed the problem.

So I will continue with the trusty v.1.50

Regards.
