commit ea2db495f92ad2cf3301623e60cb95b4062bc484 upstream. Our offset handling becomes even a little more hackish now. For some reason I do not understand all offsets as inrelative. It assumes base offset is 0x1000 but it will work for now as we make offsets relative anyway by removing base 0x1000. Should be cleaner however.

commit d53cdbb94a52a920d5420ed64d986c3523a56743 upstream. Attempting to read registers that don't exist on the SSB bus can cause hangs on some boxes. At least some b43 devices are 'in the wild' that don't have SPROMs at all. When the SSB bus support loads, it attempts to read these (non-existant) SPROMs and causes hard hangs on the box -- no console output, etc. This patch adds some intelligence to determine whether or not the SPROM is present before attempting to read it. This avoids those hard hangs on those devices with no SPROM attached to their SSB bus. The SSB-attached devices (e.g. b43, et al.) won't work, but at least the box will survive to test further patches. :-) Signed-off-by: John W.

Turns out this isn't the best way to resolve this issue. The individual patches will be applied instead. Cc: Larry Finger <Larry.Finger@lwfinger.net> Cc: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
For some Netbook computers with Broadcom BCM4312 wireless interfaces, the SPROM has been moved to a new location. When the ssb driver tries to read the old location, the systems hangs when trying to read a non-existent location. Such freezes are particularly bad as they do not log the failure. This patch is modified from commit da1fdb02d9200ff28b6f3a380d21930335fe5429 with some pieces from other mainline changes so that it can be applied to stable 2.6.34.Y.

Add support for communicating with a Sonics Silicon Backplane through a SDIO interface, as found in the Nintendo Wii WLAN daughter card. The Nintendo Wii WLAN card includes a custom Broadcom 4318 chip with a SDIO host interface.

This adds SSB functionality to register a fallback SPROM image from the architecture setup code. Weird architectures exist that have half-assed SSB devices without SPROM attached to their PCI busses. The architecture can register a fallback SPROM image that is used if no SPROM is found on the SSB device.
