9893 + * Hardware-specific External Interface I/O core definitions
9894 + * for the BCM47xx family of SiliconBackplane-based chips.
9895 + *
9896 + * The External Interface core supports a total of three external chip selects
9897 + * supporting external interfaces. One of the external chip selects is
9898 + * used for Flash, one is used for PCMCIA, and the other may be
9899 + * programmed to support either a synchronous interface or an
9900 + * asynchronous interface. The asynchronous interface can be used to
9901 + * support external devices such as UARTs and the BCM2019 Bluetooth
9902 + * baseband processor.
9903 + * The external interface core also contains 2 on-chip 16550 UARTs, clock
9904 + * frequency control, a watchdog interrupt timer, and a GPIO interface.
