+ 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.
