 * INTRODUCTION
17
 * ------------
18
 * The early RDP message definitions were held in an ARM Ltd "armdbg"
19
 * source file. Since the relevant header files were not exported
20
 * publicly as part of an ARM Ltd core tools release, it was a problem
21
 * for developers manipulating the target side of the protocol.
22
 *
23
 * For Angel, this new (ANSI 'C' clean) header file defines the ADP
24
 * protocol. The header should be useable by both host and target
25
 * systems, thus avoiding problems that can arise from duplicate
26
 * definitions. Care has been taken in the construction of this header
27
 * file to avoid any host/target differences.
28
 *
29
 * MESSAGE FORMAT
30
 * --------------
31
 * Format of the "data" section of debug and boot agent messages. This is
32
 * the standard ADP (Angel Debug Protocol) message format:
33
 *
34
 *  unsigned32 reason     - Main debug reason code.
35
 *  unsigned32 debugID    - Information describing host debug world;
36
 *                        - private to host and used in any target initiated
37
 *                          messages.
38
 *  unsigned32 OSinfo1    \ Target OS information to identify process/thread
39
 *  unsigned32 OSinfo2    / memory/world, etc. These two fields are target
40
 *                          defined.
41
 *  byte       args[n]    - Data for message "reason" code.
42
 *
43
 * NOTE: The message format is the same for single threaded debugging,
44
 * except that the "OSinfo" fields should be -1 (0xFFFFFFFF). Even
45
 * single-threaded debugging *MAY* have different host specified
46
 * debugID values, so the Angel debug system will preserve the "debugID"
47
 * information for replies, and the relevant asynchronous target-to-host
48
 * messages. The "debugID" is defined by the host-end of the
49
 * protocol, and is used by the host to ensure that messages are
50
 * routed to the correct handler program/veneer.
51
 *
52
 * The reason there are two target specified "OSinfo" words is because
53
 * thread identifiers may not be unique when processes/tasks have
54
 * private virtual address spaces. It allows more flexibility when
55
 * supporting multi-threaded or O/S aware debugging.
56
 *
57
 * NOTE: The reason that there is no "size" information, is that the
58
 * message IDs themselves encode the format of any arguments. Also it
59
  * would be a duplication of information used by the physical
60
 * transport layer (which is distinct from this logical message
61
 * layer). Any routing of messages through programs, hosts,
62
 * etc. should be performed at the physical layer, or the boundaries
63
 * between physical layers. i.e. packet received on socket in host,
64
 * and transferred to serial packet for passing on down the line.
65
 *
66
 * NOTE: Pointers aren't passed in messages because they are dangerous in
67
 * a multi-threaded environment.
68
 *
69
 * ADP REASON CODE
70
 * ---------------
71
 * The message reason codes contain some information that ties them to
72
 * the channel and direction that the message will be used with. This
73
 * will ensure that even if the message "#define name" is not
74
 * completely descriptive, the message reason code is.
75
 *
76
 *      b31    = direction. 0=Host-to-Target; 1=Target-to-Host;
77
 *      b30-28 = debug agent multi-threaded control (see below)
78
 *      b27-24 = reserved. should be zero.
79
 *      b23-16 = channelid. The fixed Angel channel number
80
 *               (see "channels.h").
81
 *      b15-0  = message reason code.
82
 *
83
 * It is unfortunate that to aid the error-checking capabilities of
84
 * the Angel communications we have changed the message numbers from
85
 * the original ARM Ltd RDP. However this also has benefits, in that
86
 * the Angel work is meant to be a clean break.
87
 *
88
 * However, it isn't so bad since even though the numbers are
89
 * different, the majority of the reason codes have exactly the same
90
 * functionality as the original RDP messages.
91
 *
92
 * NOTES
93
 * -----
94
 * It would be ideal to use "rpcgen" (or some equivalent) to
95
 * automatically maintain compatibility between the target and host
96
 * ends of the protocol. However, ARM Ltd expressed that the message
97
 * handling should be hand-coded, to avoid dependance on external
98
 * tools.
99
 *
100
 * All other channels have undefined data formats and are purely
101
 * application defined. The C library "_sys_" support will provide a
102
 * veneer to perform message block operations as required.
103
 *
104
 * It is IMPLIED that all of the ADP messages will fit within the
105
 * buffer DATASIZE. This has a minimum value, calculated from
106
 * BUFFERMINSIZE.
107
 *
108
 * All messages are passed and received to the channel system in little
109
 * endian order (ie. use little endian order when writing a word as
110
 * a sequence of bytes within a message).
111
 *
112
 * A reply / acknowledgement to an ADP message is always sent and has the
113
 * same reason code as the original except that the TtoH / HtoT bit is
114
 * reversed.  This makes it simple to check that the reply really
115
 * is a reply to the message which was just sent!  [Boot Channel messages
116
 * also require that this protocol is used].

 * agent, even if they don't have support for either the single- or
231
 * multi-threaded debug agents.
232
 *
233
 * The way the BOOT channel will be used on startup will be as follows:
234
 *
235
 * a) Target board is powered up before host debugger is invoked
236
 *
237
 * After switching on the target and initialisation is completed the
238
 * target will send an ADP_Booted or ADP_Reset message.  The debugger
239
 * has not been started yet so this message will not be received.  In
240
 * a serial world this makes it important that any buffers on the host
241
 * side are flushed during initialisation of the debugger, and in an
242
 * Ethernet world it makes it important that the target can cope with the
243
 * message not being received.
244
 *
245
 * Eventually the Debugger will be started up and will send an
246
 * ADP_Reboot or ADP_Reset request.  The target will respond to this with
247
 * an ADP_Reboot or ADP_Reset acknowldege and will then reboot, finally
248
 * sending an ADP_Rebooted when it has done all it needs to do (very little
249
 * in the case of ADP_Reset, but completely rebooting in the case of
250
 * ADP_Reboot).  Note that it is important that an ADP_Rebooted message is
251
 * sent so that the Debugger does not attempt to send any data after it has
252
 * made a request to ADP_Reboot and before it receives an ADP_Rebooted, as
253
 * data can be lost be the target during this time.
254
 *
255
 * The target and host are now ready to start a debug session.
256
 *
257
 * b) Target board is powered up after host debugger is invoked
258
 *
259
 * The debugger will send an ADP_Reboot or ADP_Reset request, but will
260
 * receive no reply until the target is powered up.
261
/ *
262
 * When the target is powered up then it will send an ADP_Rebooted
263
 * message to the debugger.  The debugger should accept this message
264
 * even though it has received no ADP_Reboot or ADP_Reset acknowldege message
265
 * from the target.
266
 *
267
 * The target and host are now ready to start a debug session.
268
 *
269
 *
270
 * If at any point during the bootup sequence and ADP messages are
271
 * sent down the S_DBG channel then they should be responded to with a
272
 * RDI_NotInitialised error. [This should never happen however].
273
 *
274
 * An ADP_Boot or ADP Rebooted message should be accepted at
275
 * any point, since it is possible for a catastrophe to occur (such as
276
 * disconnecteing the host and target during a debug message) which
277
 * requires that one or other end be reset.
