/*
 * The PLUTO controller has 4 proms (0-3).  Prom 1-3 are writeable and are
 * soldered to the board while prom 0 is not writeable but socketed. The
 * following items are placed in the PLUTO prom set:
 *	- POST0		-Power On Self Test code.  This code goes in
 *			 pluto_prom0 and may not be modified in the field.
 *			 It contains serial port downloading code.
 *	- FUNC		-Pluto Functional code (SPARC)
 *	- SOC		-SOC microcode
 *	- ISP		-ISP microcode
 *	- OBP		-Open Boot Prom code
 *	- Date Code	-date/time of prom creation.
 *	- WWN		- World Wide Name
 *
 *
 * This utility creates the writeable prom images for PLUTO.  Three prom images
 * are created: pluto_prom1, pluto_prom2, pluto_prom3.
 *
 * The following defines the layout of the 4 proms on the PLUTO controller:
 *
 * prom		offset		image
 * -----------------------------------
 * prom_0:
 *		0		POST
 * prom_1:
 *		0		FUNC
 * prom_2:
 *		0		FUNC cont'd
 * prom_3:
 *		PROM_MAGIC_OFF  PROM_MAGIC
 *		DATE_OFF	DATE_CODE
 *		WWN_OFF		WWN
 *		SOC_OFF 	SOC
 *		ISP_OFF		ISP
 *		OBP_OFF		OBP
