For each SBI extension, we: - Add a Kconfig option for it - Add the extension to sbi_ecall_exts only if the extension is enabled - Add the corresponding sbi_ecall_* object file only if the extension is enabled Special cases are as follows: - The legacy extensions are lumped together as one 'big' extension, as has always been the case in OpenSBI code. - The platform-defined vendor extensions are regarded as one extension. - The Base extension cannot be disabled. - sbi_ecall_replace implements multiple extensions, so it's not easy to avoid linking it in. Enable it always, and use #ifdef to disable/enable individual extensions.
