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. 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 -- Regards, Sudeep [1] https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/4001 arch/arm64/kernel/paravirt.c | 2 +- drivers/firmware/psci/Makefile | 2 +- drivers/firmware/psci/psci.c | 13 ++- drivers/firmware/psci/soc_id.c | 148 +++++++++++++++++++++++++++++++++ include/linux/arm-smccc.h | 23 ++++- include/linux/psci.h | 7 +- 6 files changed, 181 insertions(+), 14 deletions(-) create mode 100644 drivers/firmware/psci/soc_id.c -- 2.17.1
