How to enable trigger fire?

[AlexGJL]

There is a watchpoint enable bit in dbgwcr[0] to control watchpoint work in arm, but RV doesn't exist a similar bit to start trigger fire.
How does debugger enable a trigger? 1.use type in tdata1？but tinfo is read only，if we just implement type=6 for this trigger，type in data1 can't be 0; 2. Use m/s/u state enable，and load/store enable etc. in tdata1?

A trigger will only match if the appropriate mode bit is set and if the appropriate load/store/execute bit is set. There's no need for a top-level enable bit because there are multiple other ways to disable the trigger (and the value of m, s, u, vs, vu, load, store, and execute are all 0 on reset so triggers are disabled by default).
