I'm working in LINUX OS based ARM board.I know what all the drivers are there.but specifically i want to know to which device particular address corresponds to ports in the development board.

I don't know what's exact meaning, i want to know how to device drivers present in ARM board. Normally, all loadable modules of device driver is under /lib/modules/linux-version/kernel directory.

The drivers look exactly the same as on your Linux-based PC. The difference is that there are different buses (so also different entries in /proc). What kind of a driver do you search for?
