It did boot!, once those extra CONFIGs were added which are also required on 32
bit qemuarm, I'll send a v2!
Thanks

No objections here, a couple of suggested cleanups and a

The question: did it boot ? We should capture the boot log
in our initial commit, that way it can be a reference.

It might be worth adding a comment that these are the minimum "extra"
configurations for qemuarm64-tiny for boot. And by extra, I mean that
aren't enabled after the allnoconfig -> main tiny ktype -> the standard
qemuarm64 BSP fragments.
Actually, thinking on that more .. we could easily argue that these could
just go into the fragments included by the qemuarm64.scc.
They won't hurt those fragments, since they are larger configs anyway, and
would make sure that the main BSP fragments work in all the ktypes.

This looks fine to me. Good reuse of the existing fragments, so thanks
for that!
