From 81f9e7d6aa1dde65483387ba9e9823ef44f90435 Mon Sep 17 00:00:00 2001
From: Florian Fainelli <florian@openwrt.org>
Date: Wed, 25 Jan 2012 17:40:03 +0100
Subject: [PATCH 10/63] MIPS: BCM63XX: define internal registers offsets of the SPI controller
BCM6338, BCM6348, BCM6358 and BCM6368 basically use the same SPI controller
though the internal registers are shuffled, which still allows a common
driver to drive that IP block.
