e79c1ba84c ssb: Add SPROM fallback support
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.

b7b05fe7f9 ssb: struct device - replace bus_id with dev_name(), dev_set_name()
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".

To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.

We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.

We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

31ce12fb3e ssb: Clean up extraction of MAC addresses from SPROM
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.

f225763a7d ssb, b43, b43legacy, b44: Rewrite SSB DMA API
This is a rewrite of the DMA API for SSB devices.
This is needed, because the old (non-existing) "API" made too many bad

This introduces an almost complete SSB-DMA-API that maps to the lowlevel
bus-API based on the bustype.

2afc49015d ssb: Allow reading of 440-byte SPROM that is not rev 4
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.

4ac58469f1 ssb: Fix usage of struct device used for DMAing
This fixes DMA on architectures where DMA is nontrivial, like PPC64.
We must use the host-device's (PCI) struct device for any DMA
operation instead of the SSB device. For this we add a new
struct device pointer to the SSB device structure that will always
point to the right device for DMAing.

Without this patch b43 and b44 drivers won't work on complex-DMA
architectures, that for example need dev->archdata for DMA operations.
