Now able to run multiple ISA tests in a single simulation run
connected to remote debugger DSharp, using either hart_reset or
ndm_reset between tests to bring the system back into reset state.
All Debug Module commands working:
- dm_reset, hart_reset, ndm_reset
- break (set breakpoint)
- step
- continue (until breakpoint of 'halt' command)
- halt
- read/write GPR, FPR, CSR, memory
- elf_load
Detail: an "instruction-fetch" response from mmioplatform to core
should be an "InstFetch". This was true for successful fabric reads,
but on error responses it was wrongly returned as a "DataAccess"
response. This was causing a deadlock.
