[TF-A] Question about RME-DA in TF-A/TF-RMM/FVP

Hi all,

I find that Arm has considered "device for realms" and purposed RME-DA since last year. This is not only a concept but also includes some SMMU hardware extensions (e.g., Realm Page MMIO and DPT). Unfortunately, I only find few contents related to RME-DA in the latest FVP user guide, and nothing in TF-A/TF-RMM.

Thus, can I ask 1. Does current FVP simulate the RME-DA? 2. Will TF-A/TF-RMM supports RME-DA recently?

Sincerely, WANG Chenxu
