Matt,
Although commit 882164a4a928 ("ssb: Prevent build of PCI host features in
module") appeared to be harmless, it leads to complete failure of drivers b43.
and b43legacy, and likely affects b44 as well. The problem is that
CONFIG_SSB_PCIHOST is undefined, which prevents the compilation of the code that
controls the PCI cores of the device. See
https://bugzilla.redhat.com/show_bug.cgi?id=1572349 for details.
As the underlying errors ("pcibios_enable_device" undefined, and
"register_pci_controller" undefined) do not appear on the architectures that I
have tested (x86_64, x86, and ppc), I suspect something in the arch-specific
code for your setup (MIPS?). As I have no idea on how to fix that problem, would
the following patch work for you?
diff --git a/drivers/ssb/Kconfig b/drivers/ssb/Kconfig
