From this release onwards, secure lockdown of the FPD, PL, SoC, and
LPD domains is available. The sequence of secure lockdown for these domains is part
of PMC_DATA.CDO as a proc
command. The sequence is
under SECURE_LOCKDOWN marker in PMC_DATA.CDO. The secure lockdown proc reserved ID
is 0x80000000. If the PLM finds a proc
with this
ID, it stores the sequence in this proc
to a
reserved PMC RAM (3 KB is reserved for storing procs in PMC RAM from 0xF2016000
address) location. This sequence is executed by the PLM whenever a secure lockdown
occurs. If the execution fails, the PLM logs the error and continues with the
remaining sequences. See
Versal Adaptive SoC Security Manual (UG1508)
(registration required) for more details.
Note: For SSI technology, only SoC and PL domains
sequence is supported.
