Hi Vadim,
Thanks for your followup and attention to this matter. More below.

The upstream Linux kernel contains a quirk matching entry that looks for
"THRX". Therefore, you have already agreed (as of at least January) that
this is the prefix that you will use in any firmware updates to support
the latest upstream Linux kernel. Please register this prefix promptly.
And from what I know for now - we wont going to register this
since we have already regsitered "CAV" prefix for that. And this was the part
of our discussion also.
We had a bit long review of proper implementation of legacy firmware support,
so my apologise on that.
Please take a look at link to the patchset posted by Tomasz.

I'll let others comment on the suitability of taking that for upstream.
So the FW will be updated accordingly.
Indeed.
Yes, it is now contains "CAVxxx" as _HID for device config object.
Which is different from the version that was merged into upstream. That
should never have happened. It will never happen again. I have spent some
time over the past few days ensuring folks understand that I will not
allow a repeat of this to occur the next time around. We will have
platforms that are bulletproof and supported by upstream with any
errata fixes in a very carefully controlled manner. There will
under no circumstances ever be a situation like this again.
We are still evaluating the merits of registering the values that
appeared in v4.10, and not changing them. We should know more in a
couple of days.
The version Bjorn merged looks for "THRX". This is the version that you will
use, and you will promptly register that prefix with UEFI and provide fixes
for existing firmware to correctly use the solution that is upstream.
Cavium FW is updated accordingly to use already registered prefix.
For existent FW legacy support is posted by Tomasz.
I'm watching this to ensure it's cleaned up properly.
Jon.
