[TF-A] Re: Is there any development roadmap(plan) for the Arm CCA features?

Hi Sangwan, Yes, TF-A supports FEAT_RME since v2.6 although the support is marked experimental. The `rme_prototype` branch is deprecated and is not updated anymore. We are expecting the RMM specification to be published sometime in second half of the year and this will be followed by a reference RMM implementation in tf.org.

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
