2015-12-16ssb: pick SoC invariants code from MIPS BCM47xx archRafał Miłecki1-0/+3
There is code in ssb fetching "invariants" that is basically a set of board specific data. Every host requires its own implementation of reading function. In ssb we have support for PCI, PCMCIA & SDIO. For some (historical?) reason code reading "invariants" for SoC was placed in arch code and provided by a callback. This is not needed nowadays, so lets move that into ssb. This way we keep all "invariants" functions in a single module making code cleaner.

2015-10-28ssb: pick PCMCIA host code support from b43 driverRafał Miłecki1-0/+9
ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO. Every ssb bus contains cores AKA devices. The main idea is to have ssb driver scan/initialize bus and register ready-to-use cores. This way ssb drivers can operate on a single core mostly ignoring underlaying details. For some reason PCMCIA support was split between ssb and b43. We got PCMCIA host device probing in b43, then bus scanning in ssb and then wireless core probing back in b43. The truth is it's very unlikely we will ever see PCMCIA ssb device with no 802.11 core but I still don't see any advantage of the current architecture. With proposed change we get the same functionality with a simpler architecture, less Kconfig symbols, one killed EXPORT and hopefully cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb specific code in ssb driver. This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We already use similar solution with b43_pci_bridge.c. I didn't use "b43" in name of this new file as in theory any driver can operate on wireless core.

2012-12-06ssb: register watchdog driverHauke Mehrtens1-0/+10
Register the watchdog driver to the system if it is a SoC. Using the watchdog on a non SoC device, like a PCI card, will make the PCI card die when the timeout expired, but starting it again is not supported by ssb.

2011-05-19SSB: Change fallback sprom to callback mechanism.Hauke Mehrtens1-1/+2
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.

2009-11-24ssb: Fix SPROM writingMichael Buesch1-2/+10
The SPROM writing routines were broken since we rewrote the suspend handling on wireless devices, because SPROM writing depended on suspend.

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.

2007-10-11[SSB]: add Sonics Silicon Backplane bus supportMichael Buesch1-0/+136
SSB is an SoC bus used in a number of embedded devices. The most well-known of these devices is probably the Linksys WRT54G, but there are others as well.
