NetBSD 10.0 RC1 issues on Raspberry Pi

[Denis Ovsienko <denis%ovsienko.info@localhost>]

Hello list.

One of the features of the upcoming NetBSD 10.0 is supposed to be
support for Raspberry Pi 4.  For my use case this would be a welcome
feature, which would remove my current dependency on RPI3B(+) (I prefer
to use release versions when possible).  However, my test result shows
there is at least one combination of RPI4B-8GB hardware revision and
EEPROM that is not compatible with NetBSD 10.0 RC1.

The board is RPI4B-8GB rev. 1.5 (0xd03115) upgraded to the latest
stable EEPROM from 2023-01-11.  The problem reproduces for both
arm64.img.gz and arm64mbr.img.gz as follows (the messages appear on the
HDMI output, but not on the serial console, so this is a copy from a
monitor shot):

On RPI3B the same SD card with arm64.img.gz boots successfully, as it
used to be the case with NetBSD 9.3.  I did not do any more substantial
testing, but this crash dump on poweroff looks new:
