62 * Flash access can be enabled, with the side effect
63 * of disabling access to GPIO LED on GPIO0[20] which
64 * reuse one of the parallel flash chip select lines.
65 * Also the default firmware on the machine has the
66 * problem that since it uses the flash, the two LEDS
67 * on the right become numb.
