GPIO Overview.

Software to detect active GPIO's on startup. vDorst made a simple routine to check which of the GPIO's are set as output by the bootloader to give me an idea which GPIO's are used. Because all the referance code are unclear with gpio's are used. Plus it strongly depends on the hardware of course. This routine starts early in the kernel before setting up anything. See Commit: https://github.com/vDorst/buildroot-linux-kernel-m3/commit/c23b5a8c33941258d023d7f587cea333d98502ae#L0R647
