/*
* Hardware-specific External Interface I/O core definitions
* for the BCM47xx family of SiliconBackplane-based chips.
*
* 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
* baseband processor.
* The external interface core also contains 2 on-chip 16550 UARTs, clock
* frequency control, a watchdog interrupt timer, and a GPIO interface.
