Hi,

Will AMD submit to maintain this layer? What happens if the
maintainer will leave AMD? TBH, personally, I don't like to
maintain such a niche feature.
I'd really like to see some use cases and performance reports for
this, like actual boards (and no evaluation boards don't count). Why
wouldn't someone just use an octal flash?
And as already mentioned there is also mtdcat, which seems to
duplicate some features?
