Modification History for NEC R94A (MIPS R4400):

	H000	Thu Sep  8 10:32:42 JST 1994	kbnes!kishimoto
		- New HalpCreateEisaPCIStructures()
		- Del HalpCreateEisaStructures()
		- New function HalpEisaPCIDispatch()
		- Del function HalpEisaDispatch()
	L000	Thu Oct 13 18:09:33 JST 1994	kbnes!kuriyama(A)
	        for BBM LED
	        - Add HalpDisplayLED
		- Add HalpLEDDisplayLock
		- Add HalpLEDControlBase;
	L002	Mon Oct 17 14:21:39 JST 1994    kbnes!kuriyama(A)
	        change function name EISAPCI...   EISA..
	H001	Mon Oct 17 14:45:04 JST 1994	kbnes!kishimoto
		- Del HalDisplayLED() function definitions.
		      (We call HalR94aDebugPrint() instead of that.)
	H002	Thu Oct 20 20:58:45 JST 1994	kbnes!kishimoto
		- add extern ULONG R94aBbmLEDMapped
		      for debug use only.
	H003	Fri Oct 21 15:52:32 JST 1994	kbnes!kishimoto
		- add HalR94aDebugPrint() prototype definition.
	H004	Mon Jan 16 02:28:58 1995	kbnes!kishimoto
                - add HalpPCIConfigLock
	S005	Tue Mar 07 14:55:42 JST 1995	kbnes!kuriyama (A)
		- add Dma32BitAddresses to AdapterObject
	H006	Fri Jul 21 17:40:53 JST 1995	kbnes!kisimoto
		- merge ESM functions from J94C
	H007	Sat Aug 12 15:12:28 JST 1995	kbnes!kisimoto
                - Removed BBMLED, R94ALEDMAP code and _J94C_ definitions.
                _J94C_ definition indicates that the status of
                the dump switch can acknowledge from Self-test
                register.

        - add for merge R94A/R94A'/R94D HAL
