I actually have very few issues / complaints with that initial breakdown. It really does look to follow the standard kernel "policy" and doesn't override or add anything that isn't hardware/boot related. There's a lot of functionality included via the fragments in the configuration, but since they are all named, it is easy to scan and see what the intention of the broad enablement is. I'm ok with merging this immediately, and we can then do cleanups, etc. I'm interested in getting it booting in qemu as well, so I can do some local tests alongside the hardware support. Anyone else object to me merging this and sending the SRCREV bumps ?
