/* * 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. * * Copyright 2006, Broadcom Corporation * All Rights Reserved. * * THIS SOFTWARE IS OFFERED "AS IS", AND BROADCOM GRANTS NO WARRANTIES OF ANY * KIND, EXPRESS OR IMPLIED, BY STATUTE, COMMUNICATION OR OTHERWISE.
