[Eagle Stream][SPR] How to enable OS access to SPD controller?

Hello there,

 

I am going to develop a linux tool to access DDR5 SPD for SPR processor, but now I can not write the registers of SPD controller. For example:

 

SPR EDS Vol2, UBOX/I3C Memory Mapped I/O Registers/COMMAND_QUEUE_PORT

 

This register only support OS read access, how to enable this? I don't find the policy control registers.

 

Thanks,

Boyce
