History

Farid Khaydari 9b2a1d6c81 Add DCSR.MPRVEN support Adds DCSR.MPRVEN bit support, as specified in RISC-V External Debug Support Version 1.0.0-rc4 (https://github.com/riscv/riscv-debug-spec/releases/tag/1.0.0-rc4, see 4.9.1 Debug Control and Status). This bit allows to enable hardware virtual address translation when memory access is initiated by the debugger (see 4.1 Debug Mode, clause 2). This change: * Increases debug specification coverage, allows more detailed testing of external debuggers with Spike. * Decreases the number of required abstract commands to read virtual memory thus improving the user experience. Commit's changes: * Added MPRVEN field to DCSR register * Updated debug_rom.S to turn off MPRVEN on memory access To avoid unwanted address translation while debug_rom.S executed DCSR.MPRVEN bit has to be cleared before and restored after access.
