[U-Boot] PowerPC chipselects

Hi. Im new with embedded systems. I have a board which has a powerpc 8313 processor on it, running a linux kernel + uboot.

In the PowerPC Local Bus, there is a chipset connected to the CS02 powerpc pin. The problem is, i don't know how to map the chipset memory into powerpc main memory. What config files I have to change?

I already have a device driver for the chipset, but i dont know what memory address i should io_remap() to talk to it! The only information I have about the chipset is that it is connected to the CS02 pin, and the memory size needed is 0x8000 (32k).

Thanks
