Implement the selection of the picolibc source in a Kconfig choice as they are mutually exclusive. The following table represents the possible choices, where 'X' means that `PICOLIBC_SUPPORTED=n` and is guarded in the parent level as `PICOLIBC=n`, so we do not need to care. Module Toolchain C++ | Choice 0 0 0 | X 0 0 1 | X 0 1 0 | Toolchain only 0 1 1 | Toolchain only 1 0 0 | Module only 1 0 1 | X 1 1 0 | Toolchain/Module 1 1 1 | Toolchain only The current implementation favors `PICOLIBC_USE_TOOLCHAIN` over `PICOLIBC_USE_MODULE` whenever possible, that preference is maintained in this implementation as well - the TOOLCHAIN source will be the default choice when the toolchain supports it or when the C++ is enabled. Otherwise, fallback to MODULE. Signed-off-by: Yong Cong Sin <ycsin@meta.com> |
