This is all very recent, not all of it has been in linux-next at all, and stuff that appears to have been there has been rebased.

Why?

Linus

Responded for both in keys PR but why it came so late has a QA story behind it.

I created this week a uefi bootable buildroot target (I have tpm in the gpios) for RPi 400 and tried to get first QA round with it but I run into some systemd issues.

The upside (and the goal for doing that) is that for future releases I will bare-metal testing on aarch64 for all commits that pass through. Should have just given up on that for the time being earlier...
