A4.9 Powering up the processor without system driven L2 flush
When powering down the processor, the PDMINERVA, PDL2, and PDCPU power domains are shut down and all state is lost.
To power up the processor, apply the following sequence:
For each core in the
cluster, assert nCPUPORESET LOW.
Assert nL2RESET LOW
and hold L2RSTDISABLE LOW.
Apply power to the PDMINERVA and PDL2 domains
while keeping the signals described in steps 1 and
Release the cluster output clamps.
Continue a normal cold reset sequence.
