Exclude MMCCAM kernels from make universe

[mjg]

Summary

 They don't provide any value and are quite arbitrary.

Note arm64 GENERIC-MMCCAM was already excluded, just not the NODEBUG
variant.

The option is already build-tested with arm64 LINT kernel.

I don't think that it's true that they don't provide any value, the code path for mmccam is compile tested that way.
I'm fine for removing some if really you insist but at least one should stay.

[mjg]

is this not tested by LINT?

it looks to be in sys/arm64/conf/NOTES... I'd think that would be enough to test it... It might be a good idea to leave the 32-bit arm one enabled, but I'm agnostic on that since I know we have a lot of arm kernels.

[mjg]

huh.

now that's a bummer.

In that case I concede one kernel which uses it should be left.

I don't care which one.

Just tell me which one to keep (the 32-bit?) and accept, then I'll commit only the other two.

I think that it would be better to remove all the ones from you review from universe and add the arm64 one to it (it's more used on arm64 than armv7)

[imp]

So I'm good with the added NO_UNIVERSE tags...
We might be able to not remove the one I flagged, but I'm good either way...

(On Diff #116920)

LINT already has MMCCAM in it, so I don't think we need to remove this unless there's something I'm missing.

sys/arm64/conf/NOTES:options		MMCCAM

[mjg]

So I tested all the archs.

armv7 and amd64 don't have MMCCAM in LINT, but arm64 indeed does, consequently the code already gets build without any of -MMCCAM kernels. I'm going to revert this review back to previous form then.

If arm64 LINT build the code I'm good with it then.
