+Aeroflex Gaisler APBPS2 PS/2 Core, supporting Keyboard or Mouse.
+
+The APBPS2 PS/2 core is available in the GRLIB VHDL IP core library.
+
+Note: In the ordinary environment for the APBPS2 core, a LEON SPARC system,
+these properties are built from information in the AMBA plug&play and from
+bootloader settings.
+
+Required properties:
+
+- name : Should be "GAISLER_APBPS2" or "01_060"
+- reg : Address and length of the register set for the device
+- interrupts : Interrupt numbers for this device
+
+For further information look in the documentation for the GLIB IP core library:
+http://www.gaisler.com/products/grlib/grip.pdf
