Yes, after enabling that it works. With the tiny framework, I get
~1.5KiB reduction compared to current mainline.

I can successfully boot with your v2 patch applied with the standard and
the tiny framework. However, allow me some more time to check SFDP (and
maybe BAR) and also to check that the correct opcodes are used
(stateless 4-byte opcodes should be used).
