This is not a complete implementation yet with a lot of components
still missing but enough for the U-Boot firmware to start and to boot
a Linux kernel or AROS.

I'm not thrilled with having a machine type that can't be used without
extracting a bootloader image from somewhere, but from the other
thread that's not easy to fix.

This is not meant to be like that and I'd like to also submit the u-boot image once we figure out how to do it. Especially because the boot loader one can extract from the updater is buggy but here's a fixed binary that works here: http://zero.eik.bme.hu/~balaton/qemu/

U-Boot is GPL so we would need to include the source as well (the README in the link above contain the source URL and the patches needed are there as well). If there's no easy way to host it in the QEMU repo I could put it in my own git repo and submit a patch to use that as a submodule if that's acceptable. It seems there are some firmware images that reference external git repos already but not sure what's the preferred way.

IMHO the preferred way would be to integrate sam460ex support in upstream U-Boot and just build it from there. We already mirror U-Boot on git.qemu.org and package up that tree, so packaging up one more target from there would be trivial.
