Different architectures have different boot loaders. In particular, s390x and
ppc64el are very different. The proposal is to add support for UKIs in grub2, so
that we will cover UEFI and non-UEFI machines that use grub2. For other
architectures, we can in principle do the same thing… After all, the UKI is just
a binary with a few sections appended. But it seems to early to think such
details far ahead. As extensively discussed, the support for separate initrds is
not going anyway and the proposal only targets a small subset of the amd64 space.
Also, doesn't u-boot support those architectures? The latest u-boot UEFI interface
seems to work quite well when I tried, including support for secure boot.
