From 1df71a9257dac2ea088451250c7a20a2e5e582a3 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sun, 30 Sep 2012 11:45:31 +0000 Subject: [PATCH] [brcm47xx]: bcma: use fallback sprom if sprom on card was not valid Sometimes the PCIe card indicates that it has a sprom somewhere and we are able to read the memory region, but it is empty and not valid. In these cases we should try to use the fallback sprom as a last chance.
