Changes for v8:
- Re-order SCTLR2 and TCR2 so that they are independent of MEC.
- Enable the SCTLR2 and TCR2 enable bits.
- Squash 3 smaller MEC patches together.
This still fails the RME tests, because we still need TF-A rebuilt
with ENABLE_FEAT_SCTLR2 and ENABLE_FEAT_TCR2. Pierrick, since you
have just done such a build, could you re-test with this series?
I tested that on my local Realm enabled setup and I can confirm this solved the
issue and current series works.
Both flags are needed in TF-A. ENABLE_FEAT_TCR2 is needed to boot host, and
ENABLE_FEAT_SCTLR2 is needed to boot nested guest.
I'm a bit confused because the QEMU RME tests, afaics, uses OP-TEE, not TF-A.
I've built TF-A
using the scripts in [0], enabling ENABLE_FEAT_TCR2 and ENABLE_FEAT_SCTLR2, but
no way to get
it booting. I understand we can embed a OP-TEE into the TF_A via
BL32=<optee_image> when
building TF-A. Is that what you're using?
Thanks.
Cheers,
Gustavo

As I'm off today, I'll update that properly tomorrow when I have time, and not
rush things. I'll update RME images for sbsa and virt tests + device
passthrough test, and post associated patches.
Thanks,
Pierrick
