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.
