Subject: [PATCH v4 0/7] firmware: smccc: Add basic SMCCC v1.2 + ARCH_SOC_ID support
Date: Mon, 18 May 2020 10:12:15 +0100 [thread overview]
Message-ID: <20200518091222.27467-1-sudeep.holla@arm.com> (raw)
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[3] fixing the original
implementation there.
v1[0]->v2[1]:
- 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
v2[1]->v3[2]:
- Incorporated additional comments from Steven Price in patch 5/5
and added his review tags
- Refactored SMCCC code from PSCI and moved it under
drivers/firmware/smccc/smccc.c
- Also moved soc_id.c under drivers/firmware/smccc
v3[2]->v4:
- Incorporated all the review comments from Mark R
Regards,
Sudeep
