To move logging cse lite info in ramstage would require us to move heci command implementations to common cse lib. Also, calling these commands again from ramstage would add additional time overhead. We can think of, 1) Logging the parameters only when CSE boots from RW. 2) To add an additional elog event in cse_board_reset indicating it is a cse initiated global reset. Your thoughts?

Can we move "System boot" event log to romstage? or can we have the timeline in this order ?
1. CSE lite info log, booting from RO
2. CSE initiated global reset
3. CSE lite info log, booting from RW
4. System boot
