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
assumptions on the API of the host-bus (PCI).
This introduces an almost complete SSB-DMA-API that maps to the lowlevel
bus-API based on the bustype.

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.

d625a29ba6 ssb: Add support for block-I/O
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.

c272ef4403 ssb: Convert to use of the new SPROM structure
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>.

61e115a56d [SSB]: add Sonics Silicon Backplane bus support
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.
