Hi,
This patch series adds support for SMCCCv1.2 ARCH_SOC_ID.
This doesn't add other changes added in SMCCC v1.2 yet. They will
follow these soon along with its first user SPCI/PSA-FF.
This is tested using upstream TF-A + the patch[1] fixing the original
implementation there.
v1[0]->v2:
- Incorporated comments from Steven Price in patch 5/5
- Fixed build for CONFIG_PSCI_FW=n on some arm32 platforms
- Added Steven Price's review tags
Regards,
Sudeep
