How do I find the memory map for a device?
I’m wondering where I should search for board-specific packages in the linux source code, and more clearly, memory mapping for different devices.
I’m browsing links: http://lxr.linux.no
If it’s a PCI device, lspci -vvv will tell you.
You can also check /proc/iomem and /proc/ioport separately for memory and port mappings.
