OpenSBI Kconfig Support
|
expand
|
In future, we will see more drivers in OpenSBI for system reset, serial port, power management, etc platform specific devices. We need platform specific compile time configuration to allow users control the size of OpenSBI generic firmware binaries by only enabling desired drivers. In other words, users should be allowed to restrict the set of RISC-V platforms on which OpenSBI generic firmwares built by them can run. To address above, we add Kconfig support for OpenSBI platforms using the Kconfiglib project which is a standalone kconfig parser. To try OpenSBI Kconfig support with generic platform, here are few example commands: make PLATFORM=generic <-- builds OpenSBI using "defconfig" make PLATFORM=generic menuconfig <-- launches graphical interface for changes These patches can also be found in the kconfig_v6 branch at: https://github.com/avpatel/opensbi.git Changes since v5: - Updated kconfig symbol description in PATCH14 - Included a typo fix for docs/platform/platform.md in PATCH16 - Added separate PATCH17 for typo fix in top-level makefile Changes since v4: - Added separate PATCH14 to allow user change generic platform version and default name. - Fixed libfdt compiler error using LLVM in PATCH12 Changes since v3: - Strip down the Kconfiglib sources added by PATCH1 - Removed extra "." in the top-level Makefile updated by PATCH2 Changes since v2: - Use $(FOO) instead of $FOO to access FOO environment variable in Kconfig files. - Added a new PATCH1 to include Kconfiglib v14.1.0 sources under the scripts directory of OpenSBI. Changes since v1: - Fix SPDX license specifier in new Kconfig files Anup Patel (17): scripts: Add Kconfiglib v14.1.0 under scripts directory Makefile: Add initial kconfig support for each platform Makefile: Compile lib/utils sources separately for each platform lib: utils/serial: Use kconfig for enabling/disabling drivers lib: utils/reset: Use kconfig for enabling/disabling drivers lib: utils/sys: Use kconfig for enabling/disabling drivers lib: utils/timer: Use kconfig for enabling/disabling drivers lib: utils/ipi: Use kconfig for enabling/disabling drivers lib: utils/irqchip: Use kconfig for enabling/disabling drivers lib: utils/i2c: Use kconfig for enabling/disabling drivers lib: utils/gpio: Use kconfig for enabling/disabling drivers lib: utils/fdt: Use kconfig for enabling/disabling platform: generic: Use kconfig for enabling/disabling overrides platform: generic: Use kconfig to set platform version and default name platform: Remove redundant config.mk from all platforms docs: Update documentation for kconfig support Makefile: Fix typo related to object.mk Kconfig | 23 + Makefile | 107 +- README.md | 25 +- docs/firmware/fw_dynamic.md | 2 +- docs/firmware/fw_jump.md | 4 +- docs/firmware/fw_payload.md | 4 +- docs/library_usage.md | 6 +- docs/platform/platform.md | 6 +- docs/platform_guide.md | 9 +- firmware/Kconfig | 1 + include/sbi_utils/fdt/fdt_domain.h | 9 + include/sbi_utils/fdt/fdt_pmu.h | 10 + include/sbi_utils/ipi/fdt_ipi.h | 9 + include/sbi_utils/irqchip/fdt_irqchip.h | 10 + include/sbi_utils/irqchip/imsic.h | 10 + include/sbi_utils/reset/fdt_reset.h | 12 + include/sbi_utils/serial/fdt_serial.h | 8 + include/sbi_utils/timer/fdt_timer.h | 9 + lib/utils/Kconfig | 25 + lib/utils/fdt/Kconfig | 18 + lib/utils/fdt/objects.mk | 8 +- lib/utils/gpio/Kconfig | 23 + lib/utils/gpio/objects.mk | 10 +- lib/utils/i2c/Kconfig | 23 + lib/utils/i2c/objects.mk | 10 +- lib/utils/ipi/Kconfig | 23 + lib/utils/ipi/objects.mk | 10 +- lib/utils/irqchip/Kconfig | 41 + lib/utils/irqchip/objects.mk | 22 +- lib/utils/libfdt/Kconfig | 5 + lib/utils/libfdt/objects.mk | 2 +- lib/utils/reset/Kconfig | 37 + lib/utils/reset/objects.mk | 28 +- lib/utils/serial/Kconfig | 73 + lib/utils/serial/objects.mk | 44 +- lib/utils/sys/Kconfig | 13 + lib/utils/sys/objects.mk | 4 +- lib/utils/timer/Kconfig | 23 + lib/utils/timer/objects.mk | 10 +- platform/andes/ae350/Kconfig | 8 + platform/andes/ae350/config.mk | 36 -
