Hi,

I replied on one of the patches. Not sure doing this through quirks is the
right way right now -- unless we expect a lot more quirks over time, and/or if
this is an "enhancement" that other vendors are also likely to pick up.

I saw.  We originally tried adding our own calls, but with the advent of the
arm_smccc call it was nice to be able to leverage that instead of adding a whole
new copy of the thing.  And people didn't like the original implementation all
that much because it somewhat abused the arm_smccc register conventions.

If we added our own, it'd be a copy of the arm one with the extra register
access.

Andy

Yep. Sorry to put you in a tight spot, but since Will was rejecting my
feedback, he gets to merge the code the way he wants it to look like.

Unless I hear otherwise I'm assuming the rest of the code in this pull
request is either going in with those changes, or will be submitted
once the dependent changes have landed upstream.


Thanks!
