Ok. I didn't pay enough attention to the commit message.

And no, trapping works. Having only CPU port 5 defined on the devicetree
will cause the CPU_PORT bits to be set to port 5. There's only a problem
when multiple CPU ports are defined.

Got it. Then this is really not a problem, and the commit message frames
it incorrectly.

Actually this patch fixes the issue it describes. At the state of this patch, when multiple CPU ports are defined, port 5 is the active CPU port, CPU_PORT bits are set to port 6.

Once "the patch that prefers port 6, I could easily find the exact name but your mail snipping makes it hard" is applied, this issue becomes redundant.


So how about settling on that as a more modest Fixes: tag, and
explaining clearly in the commit message what's affected?

I don't see anything to change in the patch log except addressing Russell's
comments.

Ok. I see Russell has commented on v4, though I don't see that he particularly
pointed out that this fixes a problem which isn't yet a problem. I got lost in
all the versions. v2 and v3 are out of my inbox now :)

All good, I had to quickly roll v3 as v2 had wrong author information and I couldn't risk getting v2 applied.
