("[PATCH v2 00/36] target/arm: Reorg VHE redirection")
Changes from v4:
- Master now includes FEAT_ATS1A.
- Rebase on VHE reorg
- Trivial adjustments to S1PIE and GCS regs for REG12 redirect.
- Simplifies EXLOCK access test.
- Migration fixes based on review.
Note that tests/functional/aarch64/test_rme_* will fail.
The TF-A images need updating again for at least FEAT_S1PIE
(EL1 accessing PIRE0_EL1 trapping to EL3 is the fatal fault).
I'm toying with updating the QEMU build to match the FVP build,
so that all features are runtime enabled.
