I think migrating other architectures to use the same code should be
a separate effort from adding a generic implementation that can be
used by arm64. It's probably a good idea to have patches to convert
arm32 and/or microblaze.
Let me reiterate that I am 100% in favor of replacing arch-specific
code with more generic implementations.
However, I am not 100% in favor of doing it as separate efforts
(although maybe I could be convinced). The reasons I hesitate are
that (1) if only one architecture uses a new "generic" implementation,
we really don't know whether it is generic enough, (2) until I see the
patches to convert other architectures, I have to assume that I'm the
one who will write them, and (3) as soon as we add the code to
drivers/pci, it becomes partly my headache to maintain it, even if
only one arch benefits from it.
Please don't think I'm questioning anyone's intent or good will. It's
just that I understand the business pressures, and I know how hard it
can be to justify this sort of work to one's management, especially
after the immediate problem has been solved.
I understand your concern. I guess the only way to prove my good intentions
is to shut up and show the code.
