This series depends on Sricharan's tmel-qmp mailbox driver series v2 [1]. - Secure PIL is signed, split firmware images which only TrustZone (TZ) can authenticate and load. Linux kernel will send a request to TZ to authenticate and load the PIL images. - When secure PIL support was added to the existing wcss PIL driver earlier in [2], Bjorn suggested not to overload the existing WCSS rproc driver, instead post a new driver for PAS based IPQ WCSS driver. This series adds a new secure PIL driver for the same. - Also adds changes to scm to pass metadata size as required for IPQ5332, reposted from [3].

Added ipq5424 APCS comatible required. - added changes to scm call to pass metadata size as equired for IPQ5332. changes in v2: - Removed dependency of this series to q6 clock removal series as recommended by Krzysztof Gokul Sriram Palanisamy (3): dt-bindings: mailbox: qcom: Add IPQ5424 APCS compatible mailbox: qcom: Add support for IPQ5424 APCS IPC arm64: dts: qcom: ipq5424: add nodes to bring up q6 Manikanta Mylavarapu (4): firmware: qcom_scm: ipq5332: add support to pass metadata size dt-bindings: remoteproc: qcom: document hexagon based WCSS secure PIL arm64: dts: qcom: ipq5332: add nodes to bringup q6 arm64: dts: qcom: ipq9574: add nodes to bring up q6 Vignesh Viswanathan (1): remoteproc: qcom: add hexagon based WCSS secure PIL driver .../mailbox/qcom,apcs-kpss-global.yaml | 1 + .../remoteproc/qcom,wcss-sec-pil.yaml | 131 ++++++ arch/arm64/boot/dts/qcom/ipq5332.dtsi | 64 ++- arch/arm64/boot/dts/qcom/ipq5424.dtsi | 80 +++- arch/arm64/boot/dts/qcom/ipq9574.dtsi | 60 ++- drivers/firmware/qcom/qcom_scm.c | 13 +- drivers/firmware/qcom/qcom_scm.h | 1 + drivers/mailbox/qcom-apcs-ipc-mailbox.c | 1 + drivers/remoteproc/Kconfig | 22 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/qcom_q6v5_wcss_sec.c | 406 ++++++++++++++++++ 11 files changed, 775 insertions(+), 5 deletions(-) create mode 100644 Documentation/devicetree/bindings/remoteproc/qcom,wcss-sec-pil.yaml create mode 100644 drivers/remoteproc/qcom_q6v5_wcss_sec.c -- 2.34.1
