[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.

config SSB

	tristate "Sonics Silicon Backplane support"

	depends on SSB_POSSIBLE

	help

	  Support for the Sonics Silicon Backplane bus.

	  You only need to enable this option, if you are

	  configuring a kernel for an embedded system with

	  this bus.

	  It will be auto-selected if needed in other

	  environments.



	  The module will be called ssb.



	  If unsure, say N.

	help

	  This option turns off all Sonics Silicon Backplane printks.

	  Note that you won't be able to identify problems, once

	  messages are turned off.

	  This might only be desired for production kernels on

	  embedded devices to reduce the kernel size.

	  This turns on additional runtime checks and debugging
