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 return 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)
