Hello all,
This series adds some extra checks to ensure that it is not possible to
program the iATU with an address which we did not intend to use.
If these checks were in place when testing some of the earlier revisions
of Frank's doorbell patches (which did not handle fixed BARs properly),
we would gotten an error, rather than silently using an address which we
did not intend to use.
Having these checks in place will hopefully avoid similar debugging in the
future.
Kind regards,
Niklas
