The STM32 firewall framework offers a generic API for STM32 firewall controllers that is defined in their drivers to best fit the specificity of each firewall. There are various types of firewalls: -Peripheral firewalls that filter accesses to peripherals -Memory firewalls that filter accesses to memories or memory regions -No type for undefined type of firewall Signed-off-by: Gatien Chevallier --- Changes in V5: - Rename feature-domain* to access-control* - Fix index out of range in stm32_firewall_get_firewall() - Add mising "select STM32_FIREWALL" in config ARCH_STM32 in arch/arm/mach-stm32/Kconfig Changes in V4: - Fix documentation syntax - Put node in case of error in stm32_firewall_populate_bus() - Check firewall controller presence before using it in stm32_firewall_controller_register() Changes in V2: - Support multiple entries for "feature-domains" property. Change stm32_firewall_get_firewall() to do so. - Better handle the device-tree parsing using phandle+args APIs and phandle iterator. - Remove "resource firewall" type - Rephrase STM32_FIREWALL description in the bus Kconfig and remove useless default value - Add missing EXPORT_SYMBOL_GPL - Remove useless stm32_firewall_get_id() API - Add a field for the name of the firewall entry in the stm32_firewall_controller structure - Minor fixes on some traces level (err -> debug) - Fix licenses to GPL-2.0-only - Fix stm32_firewall_get_firewall() description - Rephrase some sentences to better emphasize this is STM32-specific - Switch to list_for_each_entry() in stm32_firewall_controller_unregister() as we only expect one firewall controller instance per device. The loop just breaks when found - Do not register the firewall controller if it is already registered to the framework MAINTAINERS | 5 + arch/arm/mach-stm32/Kconfig | 1 + arch/arm64/Kconfig.platforms | 1 + drivers/bus/Kconfig | 9 + drivers/bus/Makefile | 1 + drivers/bus/stm32_firewall.c | 294 ++++++++++++++++++++++ drivers/bus/stm32_firewall.h | 83 ++++++ include/linux/bus/stm32_firewall_device.h | 141 +++++++++++ 8 files changed, 535 insertions(+) create mode 100644 drivers/bus/stm32_firewall.c create mode 100644 drivers/bus/stm32_firewall.h create mode 100644 include/linux/bus/stm32_firewall_device.h diff --git a/MAINTAINERS b/MAINTAINERS index b19995690904..c2c362929673 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -20299,6 +20299,11 @@ T: git git://linuxtv.org/media_tree.git F: Documentation/devicetree/bindings/media/i2c/st,st-mipid02.yaml F: drivers/media/i2c/st-mipid02.c +ST STM32 FIREWALL +M: Gatien Chevallier +S: Maintained +F: drivers/bus/stm32_firewall.c + ST STM32 I2C/SMBUS DRIVER M: Pierre-Yves MORDRET M: Alain Volmat diff --git a/arch/arm/mach-stm32/Kconfig b/arch/arm/mach-stm32/Kconfig index 98145031586f..ae21a9f78f9c 100644 --- a/arch/arm/mach-stm32/Kconfig +++ b/arch/arm/mach-stm32/Kconfig @@ -12,6 +12,7 @@ menuconfig ARCH_STM32 select PINCTRL select RESET_CONTROLLER select STM32_EXTI + select STM32_FIREWALL help Support for STMicroelectronics STM32 processors. diff --git a/arch/arm64/Kconfig.platforms b/arch/arm64/Kconfig.platforms index 6069120199bb..5a46e90f1e4e 100644 --- a/arch/arm64/Kconfig.platforms +++ b/arch/arm64/Kconfig.platforms @@ -293,6 +293,7 @@ config ARCH_STM32 select ARM_SMC_MBOX select ARM_SCMI_PROTOCOL select COMMON_CLK_SCMI + select STM32_FIREWALL help This enables support for ARMv8 based STMicroelectronics STM32 family, including: diff --git a/drivers/bus/Kconfig b/drivers/bus/Kconfig index c98dd6ca2629..6c8d0725f193 100644 --- a/drivers/bus/Kconfig +++ b/drivers/bus/Kconfig @@ -163,6 +163,15 @@ config QCOM_SSC_BLOCK_BUS i2c/spi/uart controllers, a hexagon core, and a clock controller which provides clocks for the above. +config STM32_FIREWALL + bool "STM32 Firewall framework" + depends on ARCH_STM32 || COMPILE_TEST + help + Say y to enable STM32 firewall framework and its services.
