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[2] 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: - 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 Regards, Sudeep [0] https://lore.kernel.org/r/20200430114814.14116-1-sudeep.holla@arm.com/ (local) [1] https://lore.kernel.org/r/20200504092905.10580-1-sudeep.holla@arm.com/ (local) [2] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/4002 Sudeep Holla (7): firmware: smccc: Add HAVE_ARM_SMCCC_DISCOVERY to identify SMCCC v1.1 and above firmware: smccc: Update link to latest SMCCC specification firmware: smccc: Add the definition for SMCCCv1.2 version/error codes firmware: smccc: Drop smccc_version enum and use ARM_SMCCC_VERSION_1_x instead firmware: smccc: Refactor SMCCC specific bits into separate file firmware: smccc: Add function to fetch SMCCC version firmware: smccc: Add ARCH_SOC_ID support MAINTAINERS | 9 ++ arch/arm64/kernel/paravirt.c | 2 +- drivers/firmware/Kconfig | 6 +- drivers/firmware/Makefile | 3 +- drivers/firmware/psci/psci.c | 21 +--- drivers/firmware/smccc/Kconfig | 25 +++++ drivers/firmware/smccc/Makefile | 4 + drivers/firmware/smccc/smccc.c | 30 ++++++ drivers/firmware/smccc/soc_id.c | 168 ++++++++++++++++++++++++++++++++ include/linux/arm-smccc.h | 34 ++++++- include/linux/psci.h | 7 -- 11 files changed, 278 insertions(+), 31 deletions(-) create mode 100644 drivers/firmware/smccc/Kconfig create mode 100644 drivers/firmware/smccc/Makefile create mode 100644 drivers/firmware/smccc/smccc.c create mode 100644 drivers/firmware/smccc/soc_id.c -- 2.17.1 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
