First, you will need a few things.
(1) My latest branch at https://github.com/bsdimp/freebsd/tree/boot-linuxboot
(so the boot-linuxboot branch of my freebsd tree, it's sync to Friday).

(1) a small cache of binaries. You'll need to put these into
~/stand-test-root/cache. You can find the tarball at
freefall.freebsd.org:~imp/cache.tar. You can just extract this in ~. These are
the linux kernels I'm testing with.
(3) The latest qemu-system-aarch64 (I think ports/pkg version of emulators/qemu

is recent enough). If not, I know the latest master of qemu project works.

(3) A recent enough universe that the building of stand will work for all the
architectures that I build. You can hack the ARCHES line near the top of
tools/boot/full-test.sh if need be, but you'll need at least amd64, arm64 and
maybe riscv (I don't have a good way to filter arches in this script yet, since
it's at an early state of development.

(4) Build the kernel for at least arm64 and use it as an 'override'. I do this
by sudo -E make installkernel
DESTDIR=$HOME/stand-test-root/override/arm64-aarch64 TARGET=arm64 after
building the kernel. The script is designed to use kernels and binaries from
the latest CDs to do the testing, but has a way to override the kernel and
since we need to fix arm64...

(5) You'll need to build the images. If you've done 1-5 correctly (and I've not
missed anything), then "cd <mumble>/src; sh tools/boot/full-test.sh" will create
all the images and scripts to run qemu. There should be no errors, though
warnings about zfs.ko etc missing from powerpc is fine (and ignored by the
script already).

(6) There will be a script to recreate this created in
$HOME/stand-test-root/scripts/arm64-aarch64/linuxboot-test.sh. Just run it with
'sh'. And extra args are passed to qemu, so '-s -S' for gdb and
'-d trace:gicv3\* -D /tmp/gic.log' for verbose gic tracing (spaces are important).
