*  Module Description:
*
*  This is the register definitions header file for PTX block.
*  It contains the register offsets and bit field definitions.

*  Revision History:
*
*  Rev:  Date:       Author:  Comments:
*  1     11/04/2002  MRC      Creation
*  2     16/04/2002  MRC      Changed Authur to Author in the header.
*  3     22/04/2002  MRC      Changed the context table register bit position
*                             to 3, to enable address to be for 64 bit fields
*  4     22/04/2002  MRC      Changed the context table mask, to ensure that
*                             the low 16 bits are all 0.
*  5     22/04/2002  MRC      Added defines for the host entries in the
*                             context table
*  6     24/04/2002  MRC      added defines for large and small headers
*  7     29/04/2002  MRC      Changes following code review.
*  8     07/05/2002  MRC      Changed enum to use uppercase
*  9     20/06/2002  MRC      Updated
*  10    11/08/2002  GC       Swapped l3_length position values
*  11    31/10/2002  MRC      Added variants + minor fixes
