++ * Hardware-specific External Interface I/O core definitions

++ * The External Interface core supports a total of three external chip selects
++ * supporting external interfaces. One of the external chip selects is
++ * used for Flash, one is used for PCMCIA, and the other may be
++ * programmed to support either a synchronous interface or an
++ * asynchronous interface. The asynchronous interface can be used to
++ * support external devices such as UARTs and the BCM2019 Bluetooth

++ * The external interface core also contains 2 on-chip 16550 UARTs, clock
++ * frequency control, a watchdog interrupt timer, and a GPIO interface.
