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 [0] https://lore.kernel.org/r/20200430114814.14116-1-sudeep.holla@arm.com/ (local) [1] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/4001 Sudeep Holla (5): arm/arm64: smccc: Update link to latest SMCCC specification arm/arm64: smccc: Add the definition for SMCCCv1.2 version/error codes arm/arm64: smccc: Drop smccc_version enum and use ARM_SMCCC_VERSION_1_x instead firmware: psci: Add function to fetch SMCCC version arm/arm64: smccc: Add ARCH_SOC_ID support arch/arm64/kernel/paravirt.c | 2 +- drivers/firmware/psci/Kconfig | 9 ++ drivers/firmware/psci/Makefile | 1 + drivers/firmware/psci/psci.c | 13 ++- drivers/firmware/psci/soc_id.c | 165 +++++++++++++++++++++++++++++++++ include/linux/arm-smccc.h | 23 ++++- include/linux/psci.h | 7 +- 7 files changed, 207 insertions(+), 13 deletions(-) create mode 100644 drivers/firmware/psci/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
