I think we should just remove the underlying comempci access
code which is the only user of this (arch/m68knommu/kernel/comempci.c).
Nobody has used it in a very long time. And the hardware itself is
old, and completely brain-damaged by design.

A patch for removing the comempci code is below.

It's a bit suspicious that asm/elia.h is now removed since comempci.c was the only user. What's the sttus of the eLIA platform?

Only ever a handful where made, and that was in 1999.
I doubt anyone could ever use the PCI interface on it
in any useful way.


But COMEMPCI fails with a different error - this init/main.o build error is present for CONFIG_PCI=y, CONFIG_COMEMPCI=n, so the dependency of PCI on BROKEN is still required (unless it gets fixed).

Unless I am mistaken there is now no need for the CONFIG_PCI option
if selecting m68knommu. The only m68knommu platforms that had PCI
as far as I know where those that use the comempci part.

The patch looks ok to me too (acked below).

Regards
Greg

The COMEMPCI code didn't even compile.
