1 /*
2 * LED, Switch and Debug control registers for ARM Integrator Boards
4 * This is currently a stub for this functionality but at least
5 * ensures something other than unassigned_mem_read() handles access
6 * to this area.
8 * The real h/w is described at:
9 * http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0159b/Babbfijf.html
