Subject: [tf-rmm] RMM 1.0 REL alignment

Hi Everyone,
RMM specification 1.0-rel0 has been released and the PDF spec and an HTML diff relative to 1.0-eac5 are available on Arm Developer: https://developer.arm.com/documentation/den0137/1-0rel0/

As a heads up,  TF-RMM is aiming to align to this version of the specification in the next weeks. There are incompatibilities in some ABIs for REL0 compared to EAC5 specification. The work in progress RMM patches can be found here : https://review.trustedfirmware.org/q/project:TF-RMM/tf-rmm+branch:topics/rmm-1.0-rel0-rc1 and corresponding TFTF patches are here : https://review.trustedfirmware.org/q/project:TF-A/tf-a-tests+branch:topics/rmm-1.0-rel0-rc1+status:open . Suitable kernel branches will be published on this mailing list as they become available.

Best Regards

Soby Mathew
