+ARECA FIRMWARE SPEC
+===================
+
+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
+ zDRIVER 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)

+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::

-** ARECA FIRMWARE SPEC
-*******************************************************************************
-** 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 :
-** 0x00 : NOP
-** 0x01 : Get Config

-** 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
-** ->offset 0xa00 : for inbound message code message_rwbuffer
-** (driver to IOP331)
-** byte 0 : 0xaa <-- signature
-** byte 1 : 0x55 <-- signature
-** byte 2 : year (04)
