The XDR configuration is sent to the Cell BE processor via syscon's packet during booting, however you can query it at any moment.
To fetch it you need to send a packet to the system controller with service id = 0x12 and payload consisting of two zero bytes, an answer have a size of 0x84 bytes (status and data).
It contains some register values which are used during initialization of memory interface controller at startup.
