On the other hand, it doesn't seem to have any build dependency on ARCH_THUNDER,
so let's allow compile-testing to catch this kind of problem more easily.
The 64-bit dependency is needed for the use of readq/writeq.

Perhaps we should select PCI and PCI_MSI instead.
These systems cannot function without those.
Then the "depends" (and hence the patch) is correct.
A driver should not enable all of PCI if it is disabled
for some other reason.
I see your point. In that case, this patch:
