That is very un-kernellike I think, isn't it better that it gets defined as
an MTD partition?

None of it should affect registering the flash in the device tree
however, it is indeed the hardware that is there, it is a device tree.

We could discuss switching MTD and/or AFS off for EFI boots,
but it seems a bit overzealous to me.
