From b3ae52b6b0335eba547221aad2cb3c50902e3d2d Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Tue, 10 May 2011 23:31:30 +0200 Subject: SSB: Change fallback sprom to callback mechanism. Some embedded devices like the Netgear WNDR3300 have two SSB based cards without an own sprom on the pci bus. We have to provide two different fallback sproms for these and this was not possible with the old solution. In the bcm47xx architecture the sprom data is stored in the nvram in the main flash storage. The architecture code will be able to fill the sprom with the stored data based on the bus where the device was found. The bcm63xx code should do the same thing as before, just using the new API.
