I have an Overo-based project where I'd like to use some of the Display Data (DD0 .. DD23) pins as GPIO lines. In my application, there is no need for a display, so these pins
would otherwise remain unused.
Assuming I modify the default u-boot pin muxing, remove display driver support from the kernel, and use level-shifters for the I/O signals, are there any other obstacles in using these pins? Has anyone else done this?
