From 2aa088d6fd8a6c6e6020ea46b70141f0b7ccf5d2 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 27 Nov 2010 17:45:59 +0100 Subject: MIPS: BCM47xx: Fill values for b43 into SSB sprom Fill the sprom with all available values from the nvram. Most of these new values are needed for the b43 or b43legacy driver. Parts of this patch have been in OpenWRT for a long time and were written by Michael Buesch.
