LS1026/LS1046 - EVT_B[0:4], EVT_B[9] how early is "early"

HI, 

Document "QorIQ LS1046A Design Checklist , Rev. 2, 06/2020" states that EVT_B[0:4], EVT_B[9] can "can be programmed as output through EPU_EPEVTCR register early in boot code and left unconnected."

Our design left those unconnected and therefore we are keen o follow guidance and program as outputs - question we have: how early is "early"? 

Programming shall be completed before what event /condition/time? 

Thank you for the help.

Best regards

Adam
