2** ARECA FIRMWARE SPEC
3*******************************************************************************
4** Usage of IOP331 adapter
5** (All In/Out is in IOP331's view)
6** 1. Message 0 --> InitThread message and retrun code
7** 2. Doorbell is used for RS-232 emulation
8** inDoorBell : bit0 -- data in ready
9** (DRIVER DATA WRITE OK)
10** bit1 -- data out has been read
11** (DRIVER DATA READ OK)
12** outDooeBell: bit0 -- data out ready
13** (IOP331 DATA WRITE OK)
14** bit1 -- data in has been read
15** (IOP331 DATA READ OK)
16** 3. Index Memory Usage
17** offset 0xf00 : for RS232 out (request buffer)
18** offset 0xe00 : for RS232 in (scratch buffer)
19** offset 0xa00 : for inbound message code message_rwbuffer
20** (driver send to IOP331)
21** offset 0xa00 : for outbound message code message_rwbuffer
22** (IOP331 send to driver)
23** 4. RS-232 emulation
24** Currently 128 byte buffer is used
25** 1st uint32_t : Data length (1--124)
26** Byte 4--127 : Max 124 bytes of data
27** 5. PostQ
28** All SCSI Command must be sent through postQ:
29** (inbound queue port) Request frame must be 32 bytes aligned
30** #bit27--bit31 => flag for post ccb
31** #bit0--bit26 => real address (bit27--bit31) of post arcmsr_cdb
32** bit31 :
33** 0 : 256 bytes frame
34** 1 : 512 bytes frame
35** bit30 :
36** 0 : normal request
37** 1 : BIOS request
38** bit29 : reserved
39** bit28 : reserved
40** bit27 : reserved
41** ---------------------------------------------------------------------------
42** (outbount queue port) Request reply
43** #bit27--bit31
44** => flag for reply
45** #bit0--bit26
46** => real address (bit27--bit31) of reply arcmsr_cdb
47** bit31 : must be 0 (for this type of reply)
48** bit30 : reserved for BIOS handshake
49** bit29 : reserved
50** bit28 :
51** 0 : no error, ignore AdapStatus/DevStatus/SenseData
52** 1 : Error, error code in AdapStatus/DevStatus/SenseData
53** bit27 : reserved
54** 6. BIOS request
55** All BIOS request is the same with request from PostQ
56** Except :
57** Request frame is sent from configuration space
58** offset: 0x78 : Request Frame (bit30 == 1)
59** offset: 0x18 : writeonly to generate
60** IRQ to IOP331
61** Completion of request:
62** (bit30 == 0, bit28==err flag)
63** 7. Definition of SGL entry (structure)
64** 8. Message1 Out - Diag Status Code (????)
65** 9. Message0 message code :

106** RS-232 Interface for Areca Raid Controller
107** The low level command interface is exclusive with VT100 terminal
108** --------------------------------------------------------------------
109** 1. Sequence of command execution
110** --------------------------------------------------------------------
111** (A) Header : 3 bytes sequence (0x5E, 0x01, 0x61)
112** (B) Command block : variable length of data including length,
113** command code, data and checksum byte
114** (C) Return data : variable length of data
115** --------------------------------------------------------------------
116** 2. Command block
117** --------------------------------------------------------------------
118** (A) 1st byte : command block length (low byte)
119** (B) 2nd byte : command block length (high byte)
120** note ..command block length shouldn't > 2040 bytes,
121** length excludes these two bytes
122** (C) 3rd byte : command code
123** (D) 4th and following bytes : variable length data bytes
124** depends on command code
125** (E) last byte : checksum byte (sum of 1st byte until last data byte)
126** --------------------------------------------------------------------
127** 3. Command code and associated data
128** --------------------------------------------------------------------
129** The following are command code defined in raid controller Command
130** code 0x10--0x1? are used for system level management,
131** no password checking is needed and should be implemented in separate
132** well controlled utility and not for end user access.
133** Command code 0x20--0x?? always check the password,
134** password must be entered to enable these command.
