As stated in the issue https://github.com/openhwgroup/cva6/issues/719 the immediate field should be ignored for FENCE.I which isn't in the master (the spec also states that standard software should zero out those fields so that's probably why it went unnoticed) (line 234,235). For issue https://github.com/openhwgroup/cva6/issues/720 I just added the else on the default case which will result into an illegal instruction if no match in the cases are found (line 163, 164).
