**	Usage of IOP331 adapter
**	(All In/Out is in IOP331's view)
**	1. Message 0 --> InitThread message and return code
**	2. Doorbell is used for RS-232 emulation
**		inDoorBell :    bit0 -- data in ready
**			(DRIVER DATA WRITE OK)
**				bit1 -- data out has been read
**			(DRIVER DATA READ OK)
**		outDooeBell:    bit0 -- data out ready
**			(IOP331 DATA WRITE OK)
**				bit1 -- data in has been read
**			(IOP331 DATA READ OK)
**	3. Index Memory Usage
**	offset 0xf00 : for RS232 out (request buffer)
**	offset 0xe00 : for RS232 in  (scratch buffer)
**	offset 0xa00 : for inbound message code message_rwbuffer
**			(driver send to IOP331)
**	offset 0xa00 : for outbound message code message_rwbuffer
**			(IOP331 send to driver)
**	4. RS-232 emulation
**		Currently 128 byte buffer is used
**			1st uint32_t : Data length (1--124)
**			Byte 4--127  : Max 124 bytes of data
**	5. PostQ
**	All SCSI Command must be sent through postQ:
**	(inbound queue port)	Request frame must be 32 bytes aligned
**	#bit27--bit31 => flag for post ccb
**	#bit0--bit26  => real address (bit27--bit31) of post arcmsr_cdb
**		bit31 :
**			0 : 256 bytes frame
**			1 : 512 bytes frame
**		bit30 :
**			0 : normal request
**			1 : BIOS request
**		bit29 : reserved
**		bit28 : reserved
**		bit27 : reserved
**  ---------------------------------------------------------------------------
**	(outbount queue port)	Request reply
**	#bit27--bit31
**		=> flag for reply
**	#bit0--bit26
**		=> real address (bit27--bit31) of reply arcmsr_cdb
**			bit31 : must be 0 (for this type of reply)
**			bit30 : reserved for BIOS handshake
**			bit29 : reserved
**			bit28 :
**			0 : no error, ignore AdapStatus/DevStatus/SenseData
**			1 : Error, error code in AdapStatus/DevStatus/SenseData
**			bit27 : reserved
**	6. BIOS request
**		All BIOS request is the same with request from PostQ
**		Except :
**			Request frame is sent from configuration space
**		offset: 0x78 : Request Frame (bit30 == 1)
**		offset: 0x18 : writeonly to generate
**					IRQ to IOP331
**		Completion of request:
**			(bit30 == 0, bit28==err flag)
**	7. Definition of SGL entry (structure)
**	8. Message1 Out - Diag Status Code (????)
**	9. Message0 message code :

**    	(A) Header : 3 bytes sequence (0x5E, 0x01, 0x61)
**    	(B) Command block : variable length of data including length,
