*******************************************************************************
**                            ARECA FIRMWARE SPEC
*******************************************************************************
**	Usage of IOP331 adapter
**	(All In/Out is in IOP331's view)
**	1. Message 0 --> InitThread message and retrun 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 :
**		0x00 : NOP
**		0x01 : Get Config
**		->offset 0xa00 :for outbound message code message_rwbuffer
**		(IOP331 send to driver)
**		Signature             0x87974060(4)

**		Signature             0x87974063(4)
**		UPPER32 of Request Frame  (4)-->Driver Only
**		0x03 : Reset (Abort all queued Command)
**		0x04 : Stop Background Activity
**		0x05 : Flush Cache
**		0x06 : Start Background Activity
**			(re-start if background is halted)
**		0x07 : Check If Host Command Pending
**			(Novell May Need This Function)
**		0x08 : Set controller time

**      	RS-232 Interface for Areca Raid Controller
**      The low level command interface is exclusive with VT100 terminal
**  --------------------------------------------------------------------
**      1. Sequence of command execution
**  --------------------------------------------------------------------
**    	(A) Header : 3 bytes sequence (0x5E, 0x01, 0x61)
**    	(B) Command block : variable length of data including length,
**    		command code, data and checksum byte
**    	(C) Return data : variable length of data
**  --------------------------------------------------------------------
**    2. Command block
**  --------------------------------------------------------------------
**    	(A) 1st byte : command block length (low byte)
**    	(B) 2nd byte : command block length (high byte)
**                note ..command block length shouldn't > 2040 bytes,
**    		length excludes these two bytes
**    	(C) 3rd byte : command code
**    	(D) 4th and following bytes : variable length data bytes
**    		depends on command code
**    	(E) last byte : checksum byte (sum of 1st byte until last data byte)
**  --------------------------------------------------------------------
**    3. Command code and associated data
**  --------------------------------------------------------------------
**    	The following are command code defined in raid controller Command
**    	code 0x10--0x1? are used for system level management,
**    	no password checking is needed and should be implemented in separate
**    	well controlled utility and not for end user access.
**    	Command code 0x20--0x?? always check the password,
**    	password must be entered to enable these command.
