2009-03-05ssb: Add SPROM fallback supportMichael Buesch
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.

2009-01-29b43/ssb: Add SPROM8 extraction and LP-PHY detectionMichael Buesch
This adds detection code for the LP-PHY and SPROM extraction code for version 8, which is needed by the LP-PHY and newer N-PHY. Signed-off-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-08-29ssb: Clean up extraction of MAC addresses from SPROMLarry Finger
Only rev 1 and 2 ssb SPROMs have fields named et0mac and et1mac; however, all of the extraction routines extract pseudo data for these fields from regions that are all 1's resulting in a hardware address of FF:FF:FF:FF:FF:FF. This patch forces such a fill at the beginning of the data extraction process, and only does the formal extraction if the SPROM rev is 1 or 2.

2008-08-29ssb: Update for Rev. 5 SPROMLarry Finger
Although a revision 5 SPROM has not been seen in the wild, the open-source portion of the MIPS driver 4.150.10.5 describes its layout, which is mostly inherited from revision 4. This patch implements the differences. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Acked-by: Michael Buesch <mb@bu3sch.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-05-07ssb: Allow reading of 440-byte SPROM that is not rev 4Larry.Finger@lwfinger.net
The current code checks for the special signature that signifies a revision 4 SPROM. Now that a rev. 8 SPROM with a 440-byte length has been found that may not have any special code, this check could be relaxed. With this patch, if the CRC is incorrect for a 256-byte SPROM, the code will immediately check for a 440-byte SPROM. If there is still a CRC error, the size is set to 440 bytes, which allows dumping of most of any 512-byte SPROM if one is encountered.

2008-04-23ssb: Fix all-ones boardflagsLarry Finger
In the SSB SPROM a field set to all ones means the value is not defined in the SPROM. In case of the boardflags, we need to set them to zero to avoid confusing drivers. Drivers will only check the flags by ANDing.

2008-04-08ssb: Add support for block-I/OMichael Buesch
This adds support for block based I/O to SSB. This is needed in order to efficiently support PIO data transfers to the card. The block-I/O support is only compiled, if it's selected by the weird driver that needs it. So there's no overhead for sane devices.

2008-01-28ssb: Convert to use of the new SPROM structureLarry Finger
In disagreement with the SPROM specs, revision 3 devices appear to have moved the MAC address. Change ssb to handle the revision 4 SPROM, which is a different size. This change in size is handled by adding a new variable to the ssb_sprom struct and using it whenever possible. For those routines that do not have access to this structure, a 'u16 size' argument is added. The new PCI_ID for the BCM4328 is also added. Testing of the Revision 4 SPROM, which is used on the BCM4328, was done by Michael Gerdau <mgerdau@tiscali.de>. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.

2008-01-28ssb: Add new SPROM structure while keeping the oldLarry Finger
The SPROM's for various devices utilizing the Sonics Silicon Backplane come with various revisions. The Revision 2 SPROM inherited the data layout of 1, and Revision 3 inherited the layout of 2. The first instance of Revision 4 has now been found in a BCM4328 wireless LAN card. This device does not inherit any layout from previous versions. Although it was possible to create a data structure that kept all the old layouts, we decided to start fresh, keep only those SPROM variables that are used by the drivers that utilize ssb, and to do the conversion in such a manner that neither compilation or execution will be affected if a bisection lands in the middle of these changes, while keeping the patches as small as possible. In this patch, the sprom structures are changed while maintaining the old ones. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2007-10-10[SSB]: Use ioreadX() and iowriteX() for PCI.Michael Buesch
On a PCI bus use ioreadX() and iowriteX(). We map the I/O space with pci_iomap(), so we must use the correct accessor functions, too. readX() and writeX() are not guaranteed to accept the cookie returned from pci_iomap() (though, it currently works on most architectures).

2007-10-10[SSB]: add Sonics Silicon Backplane bus supportMichael Buesch
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. The bus is also used internally on the BCM43xx and BCM44xx devices from Broadcom. This patch also includes support for SSB ID tables in modules, so that SSB drivers can be loaded automatically.
