				//  Ver | dd mmm yyyy | Who  | Description of changes
				// =====|=============|======|===============================================
				//  1.00| 11 Sep 2003 | L.H  | Changes since previous version (v.58 Alpha)
				//      |             |      | Removed .bss, .const and .sysmem
				//      |             |      |    These are for a small memory model.  All examples
				//      |             |      |    use the large model.
				//      |             |      | Added ECANA_LAM ECANA_MOTO and ECANA_MOTS memory
				//      |             |      |    blocks.  Also allocated the register files
				//      |             |      |    to these memory blocks.
				//      |             |      | Added CSM Password locations to Page 0
				//      |             |      |    in order to program new passwords
				//      |             |      | Moved peripheral register files to DSP28_Headers_BIOS.cmd
				//      |             |      |    and DSP28_Headers_nonBIOS.cmd
				//      |             |      | Added CSM_RSVD memory section in FLASHA - this region
				//      |             |      |    should be programmed with all 0x0000 when using the CSM
