Some Exynos-based boards are running with secure firmware running in TrustZone secure world, which changes the way some things have to be initialized. This series adds support for specifying firmware operations, implements some firmware operations for Exynos secure firmware and adds a method of enabling secure firmware operations on Exynos-based boards through board file and device tree. Depends on: - ARM: EXYNOS: Add support for secondary CPU bring-up on Exynos4412 Changes since v3 ( http://thread.gmane.org/gmane.linux.kernel.samsung-soc/13442 ) - Replaced cpu_boot_reg call with cpu_set_boot_addr - Added interface documentation - Separated from Exynos4x12 secondary CPU bring-up patch Changes since v2 ( http://thread.gmane.org/gmane.linux.kernel.samsung-soc/12848 ) - Made Exynos firmware binding require address - Minor style fixes Changes since v1 ( http://thread.gmane.org/gmane.linux.kernel.samsung-soc/12583/focus=12820 ) - Changed return types of all operations to int - Defined all operations to return 0 on success, -ENOSYS when not implemented or appropriate error code on error Tomasz Figa (5): ARM: Add interface for registering and calling firmware-specific operations ARM: EXYNOS: Add support for secure monitor calls ARM: EXYNOS: Add support for Exynos secure firmware ARM: EXYNOS: Add IO mapping for non-secure SYSRAM.
