This commit introduces minimal support for the RISC-V Svrsw60t59b extension, which defines reserved bits within page-table entries for software use. This extension is slated to be part of the upcoming RVA23.1 specification. The changes involve adding the new extension to GCC’s internal definitions, an options file, and documentation, enabling the compiler to acknowledge and potentially utilize this hardware feature in future development.
