This draft PR depends on lowRISC/ibex#2232 and currently uses the source branch of that upstream PR for integration preparation & testing. That will be removed once the upstream PR has been merged.

TODO: Replace this commit by the one auto-generated by the vendor tool.

Signed-off-by: Andreas Kurth <[email protected]>
TODO: This should probably get squashed into the previous commit, so
that the repository doesn't end up in an unusable state after the
previous commit.

TODO: Insert commit SHA below once merged upstream.

The following SW-visible changes have been made since v2.0.0:
- [rtl,pmp] Allow all accesses to Debug Module in debug mode
  (lowRISC/ibex@TODO)

As these changes are backward-compatible (i.e., software that worked
before will still work) but adds additional behavior, the minor version
gets incremented.

Maybe just make a local parameter? I don't think that should be overwritten, and if, it might cause some security issue?
