DESCRIPTION

-----------
|
||||
|
||||
This SSP header is available throughout the kernel, for this
|
||||
machine/architecture, because drivers that use it may be dispersed.
|
||||
|
||||
This file was cloned from the 7952x implementation. It would be
|
||||
better to share them, but we're taking an easier approach for the
|
||||
time being.
