Yes, that is correct. I have only tested this series with the upstream
kernel, not the vendor kernel. Sorry for not pointing this out in the
cover letter.

I will state this explicitly in the next cover letter. This series
only provides the basic K3 platform initialization and start-only HSM
support needed to bring up the X100 and A100 harts. It does not include
the vendor-specific OpenSBI RPMI support required by the vendor kernel
and DT.
The relevant public documentation is available here:
CCI and PMA [1]
HSM-related power management [2]
Clock and reset [3]
SoC address map [4]
We do not currently plan to publish additional K3 hardware details.
Before doing so, we would need to reorganize the documentation and review
which parts can be made public. This is a substantial amount of work and
is not currently scheduled.
