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.

Sample

Here are example outputs from Slim consoles (only data):
