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_v4 branch at:
https://github.com/avpatel/opensbi.git
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
