Four 32-bit persistent global storage registers are available for general use. Their values are preserved after software reboot. See Global Storage Registers for more information.
The following registers are reserved.
Recommended: Xilinx recommends that you do not use reserved registers.
|Contains the ROM execution time stamp. When PLM is active, it reads these two registers to obtain the execution time of ROM. Registers can be used after loading boot PDI.
|Contains device security status, updated by ROM. PLM uses this register to determine if KAT needs to be performed.
|Used by PLM to store the TF-A handoff parameter address pointer.
|Reserved for XilPM to save the status of each power domain initialization.
|Not yet used in PLM but intended for data sharing between PLM and debugger.
