* Core-V eXtension Interface (CV-X-IF) integration (#277)
* minor fixes (#283)
* minor fix again
* Changes to make the X_if addition compatible with the golden version of the core, minus the rf_we line (#289)
* Fix remaining sec inconsistency regarding the X-IF addition (#291)
* Changes to make the X_if addition compatible with the golden version of the core, minus the rf_we line
* [rt][sec][xif] Made the length of the cve2_id_stage's rf_wdata_sel dependent on the whether the X-IF is present
* [rtl][sec][xif] Made the length of the cve2_id_stage's rf_wdata_sel dependent on the whether the X-IF is present
* Clean Verilator warning about X-IF addition while keeping the RTL SEC-safe (#292)
* Changes to make the X_if addition compatible with the golden version of the core, minus the rf_we line
* [rt][sec][xif] Made the length of the cve2_id_stage's rf_wdata_sel dependent on the whether the X-IF is present
* [rtl][sec][xif] Made the length of the cve2_id_stage's rf_wdata_sel dependent on the whether the X-IF is present
* [rtl][xif][verilator] Clean warnings about enum-logic[] width mismatch on Verilator, while keeping the design logically equivalent. This is due to the cve2_decoder's rf_wdata_sel_o signal, which has its width dependent of the X-IF.
* fix xif

* [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.
