Eclipse Webmaster requested to merge github/fork/silabs-oysteink/silabs-oysteink_dbg-num-triggers into master Nov 16, 2022

Created by: silabs-oysteink

Added support for DBG_NUM_TRIGGER parameter.If 0, the debug_triggers module will not be instantiated and any access to trigger CSR will result in an illegal instruction.

debug_triggers will instantiate DBG_NUM_TRIGGERS instances of tdata1 and tdata2 and perform instruction address match checks for any enabled triggers.

Converted trigger type 2 (mcontrol) to 6 (mcontrol6) and updated trigger match to take EXECUTE and M bit into account. (Passed modified debug_trigger_test). Reset value for tdata1 is updated to reflect mcontrol6.

Without the conversion of mcontrol -> mcontrol6, this PR is SEC clean when DBG_NUM_TRIGGERS=1.
