From 112b2e12edda60f495b57e8a1d85eb95e2662845 Mon Sep 17 00:00:00 2001
From: Hauke Mehrtens <hauke@hauke-m.de>
Date: Thu, 16 Feb 2012 23:44:26 +0100
Subject: [PATCH 199/202] MIPS: BCM47XX: provide sprom to bcma bus
On SoCs the sprom is often stored in nvram in the flashchip. This patch
registers a sprom fallback callback handler in bcma and provides the
sprom needed for this device.
