The pi4 kernel on 9p.io is now more complete, with support for
SD card (which was pleasantly standards-conforming), and ethernet
(thanks to cinap).  USB3 still missing, so useful only as a cpu
server.

On a pi4 with 4GB RAM, only 2GB will be accessible until we have
a proper implementation of kmap().

For convenience there's a bootable 9pi4cpu binary in /contrib/miller.

Needs firmware from 5 July 2019 or later.
config.txt for pi4 should 'core_freq=250' and 'device_tree='
