Use a standard Gentoo aarch64 (arm64 ) package. Add a pi kernel, the
/lib/modules directory and the /boot directory  from a raspian tarball.

I did this on a pi 3B running in 64bit mode. Once I had a bootable
system it was easy to modify and a fork from my first image is also
running on a couple of odroid 64bit systems (using the odroid boot and
kernel) and as an lxc image on a 64bit odroid n2.

Getting the /boot directory and uBoot config files sorted was the main
problem.

Use the equivalent from your local mirror.

Interesting...

I'll give that a shot. Thanks William.

I'm about to try this:

https://github.com/sakaki-/gentoo-on-rpi-64bit

for a couple of 3's and then some 4's when they turn up. Have you tried
it and it fails?

Bear in mind apparently a normal pi boot setup doesn't work on the 400.
Don't know anything about it except apparently if you stick a card for
the pi 3 or 4 in a 400, it won't boot. It needs to be optimised for the 400.

Sorry, forgot about those thingies... Took the "400" to be a typo of
"4", ie just the board....
