[PATCH v5 00/20] target/arm: Implement FEAT_RME

[Richard Henderson]

Changes for v5:
  * Enabled only by cpu property x-rme=on, not -cpu max.
  * Rebase vs SecEL2 fixes, now in master.

This doesn't have the magic RMM memory, which previous patch sets
included for booting Huawei's forked TF-A.  Upstream TF-A does not
have sufficient code to build either PLAT={qemu,qemu_sbsa} with
the RMM enabled, so that can't be tested either at the moment.

All I can say is that this doesn't appear to break anything else
with x-rme=on.  Which is less than satisfying.
