Great, thanks for testing. I'll soon send a v2, but I guess that's too
late for this merge window.

Regarding how to apply, I believe I'll have more spi-nand patches on top
of that in the next cycle, so either I apply them with your Ack and
share an immutable tag, or you apply it and give me one. Either ways
works fine for me. It's more work to create the branch/tag so I can
handle it (once we settle on the content ofc).

Cheers,
Miquèl
