+SystemReady Arm Platforms
+=========================
+
+The genericarm64 MACHINE is designed to work on standard SystemReady IR
+compliant boards with preinstalled firmware.
+
+The genericarm64 MACHINE is currently tested on the following platforms:
+
+  * Texas Instruments BeaglePlay
+
+The images built are EFI bootable disk images and can be written directly to a
+SD card for booting, for example.
