+   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.
