How to find the memory map of a device?

Question

I would like to know where in the linux source code should i search for finding the board specific packages, more clearly, the memory map of different devices.

I was browsing through the link : http://lxr.linux.no

Thanks

If it's a PCI device, lspci -vvv will show you.

You can also check /proc/iomem and /proc/ioport for memory and port mappings, respectively.
