Good morning Peter,

I mean that no matter how hard you try, there will _always_ be one
application left which needs something changed that no one had foreseen.
But that's exactly the strong point of an open source BIOS. The source
adds the last, ultimate layer of configurability.

Absolutely!!

I meant the mapping INT A --> IRQ 10 etc. I already had a patch for this
(attached) but also decided against it, because this should be generic
and _not_ done individually at the board level and the device tree is a
better place for it anyway.

I agree 100%!
