Hi,
I checked that TF-A supports FEAT_RME since v2.6.
(https://trustedfirmware-a.readthedocs.io/en/latest/change-log.html)
And those are developed on rme_prototype branch.
( https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/log/?h=topics/rm... )
But it is not updated since last year (September, 2021).
I was wondering if there is a development plan or active branch about Arm CCA features (like RME RMM).
BRs,
Sangwan Kwon
