[WIP-for-10.1 0/3] target/arm: Add FEAT_MEC to max cpu

Posted by Gustavo Romero 4 months, 2 weeks ago

This series a WIP for adding full FEAT_MEC support to arm max cpu.

It adds the FEAT_MEC registers but does not touch the translation regimes to
support the MECIDs. I'm currently looking at the possibilies to support it in
QEMU for the various translation regimes we have on Arm64.


Cheers,
Gustavo
