Subject: [PATCH v2 11/11] MIPS: BCM47XX: provide sprom to bcma bus
Date: Tue, 28 Feb 2012 00:56:14 +0100	[thread overview]
Message-ID: <1330386974-4056-12-git-send-email-hauke@hauke-m.de> (raw)
In-Reply-To: <1330386974-4056-1-git-send-email-hauke@hauke-m.de>

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.
