From mboxrd@z Thu Jan 1 00:00:00 1970 From: carlo@caione.org (Carlo Caione) Date: Wed, 18 May 2016 16:56:18 +0200 Subject: [PATCH v2 0/4] Add Amlogic secure monitor driver Message-ID: <1463583382-15614-1-git-send-email-carlo@caione.org> To: linus-amlogic@lists.infradead.org List-Id: linus-amlogic.lists.infradead.org From: Carlo Caione In the Amlogic SoCs the secure monitor calls are used for a lot of reasons: interact with the NVMEM (efuses), check the reboot reason, set USB boot, ... This driver defines a generic interface towards the secure monitor that can be used by more specialized drivers to interact with the secure monitor itself without worrying about bounce buffers managing. Changelog: v2: * All the SMC function identifiers are now in a SoC-specific header file to be included by the DTS files so the SMC commands are now defined in the DT instead to be hardcoded into the driver * Patchset is no longer an RFC * Better error management and boundary checking * s/unsigned int/u32/ * SMC call not only on CPU 0 * Fix memory leaking * s/amlogic/meson/ in the directory names Carlo Caione (4): soc: Amlogic: Add secure monitor driver soc: dt-bindings: Add secure monitor header file for GXBB ARM64: dts: amlogic: gxbb: Enable secure monitor documentation: Add secure monitor binding documentation .../devicetree/bindings/soc/meson/meson_sm.txt | 45 ++++++ arch/arm64/boot/dts/amlogic/meson-gxbb.dtsi | 7 + drivers/soc/Kconfig | 1 + drivers/soc/Makefile | 1 + drivers/soc/meson/Kconfig | 8 ++ drivers/soc/meson/Makefile | 1 + drivers/soc/meson/meson_sm.c | 155 +++++++++++++++++++++ include/dt-bindings/soc/meson-gxbb-sm.h | 44 ++++++ include/linux/soc/meson/meson_sm.h | 22 +++ 9 files changed, 284 insertions(+) create mode 100644 Documentation/devicetree/bindings/soc/meson/meson_sm.txt create mode 100644 drivers/soc/meson/Kconfig create mode 100644 drivers/soc/meson/Makefile create mode 100644 drivers/soc/meson/meson_sm.c create mode 100644 include/dt-bindings/soc/meson-gxbb-sm.h create mode 100644 include/linux/soc/meson/meson_sm.h -- 2.7.4
