+/*
+ * 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.
