* [rtl] Clear mprv on mret to non M-mode This is specification change between the v1.11 and v1.12 privileged architectures. Previously mprv wasn't altered on mret. Now if returning to a privilege level other than M mode mprv must be cleared. * [rtl, dv] Add new CSRs for latest priviledged spec This adds the following CSRs to support the v1.12 priviledged spec. - MSTATUSH - MCONFIGPTR - MENVCFG - MENVCFGH MCONFIGPTR is read only and has its value provided by a ibex_pkg parameter CSR_MCONFIGPTR_VALUE which is set to 0. Implementors can alter this value if needed. All the other CSRs ignore writes and read as 0. --------- Co-authored-by: Greg Chadwick <gac@lowrisc.org> |
