[ixp1200] [Q] I have a question about IXP SDRAM mapped into PCI bus.

Hello. I kwow that all region of IXP SDRAM is mapped into PCI bus. And I am curious about how do I read/write 'SDRAM mapped in PCI bus' using vera source. Is there a function to access that region? I think that 'VeraI2Oexp' function is used for reading/writing to SDRAM Am I right? If right, please give me more information. And can I access that address using 'variable' like below? example) int xx (allocated in SDRAM) write some data to xx Please answer my questions. Thanks
