Smcsrind/Sscsrind is an ISA extension that extends the indirect CSR access mechanism originally defined as part of the Smaia/Ssaia extensions, in order to make it available for use by other extensions without creating an unnecessary dependence on Smaia/Ssaia.
Minor update needed to document: the copyright dates should be set to 2023 as the availability via Freeze would make it a product of 2023, not 2022.
