I worked with Judith Mendez to get to the bottom of this - she shared
logs from the AM65 IDK board and we went back and forth analyzing
them, which pointed to a board-level power sequencing problem on
AM65x rather than an issue with this patch. In her words:
"So it is truly a power issue, I have a patch to fix the issue on am65x.
There is nothing wrong with your patch, coincidentally my power issue
caused am65x to fall into a weird state and your commit caught that.
So actually, thanks. I can now send my proper fix to the u-boot mailing
list."
So this patch did not introduce a regression - it actually helped uncover
a latent power-sequencing issue on the AM65x board that was
independent of this change. Judith will be sending a separate fix for the
AM65x board issue.
Thanks for the updating.
Thanks,
Peng
I'd consider this matter closed with respect to this patch. Thanks Judith
for digging into this and confirming the root cause.
Confirm on the above. No problem, thanks to you for the collab (:
