Ah.. That. I have that in a board specific file. Looks excactly like the
implementation you have (for the 8266 port) For our internal board, it
is quite different, so it should probably be in a board specific file

I think I like the _LOWER/_UPPER/OFFSET variant. And it need to be
possible to override it in board-files.
I'll work in getting the 8266 PCI support I have to be integrated into
the PQ2[F]ADS board support.
