[PATCH 3/4] ARCv2: smp: MCIP: remove debug aid to halt all cores when one halts

From: Vineet Gupta
Date: Mon Jan 16 2017 - 15:58:54 EST


This was really usefull when doing initial bringup and also for
occassional debug of software and hardware bugs. However in the new
smp-boot regime, non masters will "self" halt even for run-on-reset
configs. This will misinteract with the debug feature as in even master
will get halted when the non masters self halt.
