Search and destroy the jtag_tap_t typedef. This also cleans up a
layering violation, removing the declaration from types.h.

The number of command arguments will always be 0 or more, so use
the right type in handlers. This has a cascading effect up through
the layers, but the new COMMAND_HANDLER macros prevented total chaos.

By introducing the CMD_NAME macro, this parameter may be integrated
as args[-1] in command.[ch], without touching any other call sites.
|

|

|

By using CALL_COMMAND_HANDLER, parameters can be reordered, added, or
even removed in inherited signatures, without requiring revisiting
all of the various call sites.

Define the numerous helpers that inherit command handler parameters
using the COMMAND_HELPER macro.

Add the khz and speed_div functions to the parport interface driver.
Add the parport_toggling_time function that tells the parport driver
how long (in nanoseconds) it takes for the hardware to toggle TCK.

Without this patch, running "openocd -c 'jtag interface'" segfaults.
Now, it returns the string "undefined" when the interface is unset.
|
|
|
|
|
|
| |
Contrary to my previous assessment, some opportunities to remove forward
declarations were overlooked. Remove them by moving the definitions
of the command registration and interface structure to the end of files.

It's been about a year since these were deprecated and, in most
cases, removed. There's no point in carrying that documentation,
or backwards compatibility for "jtag_device" and "jtag_speed",
around forever. (Or a few remnants of obsolete code...)
Removed a few obsolete uses of "jtag_speed":
- The Calao stuff hasn't worked since July 2008. (Those Atmel
targets need to work with a 32KHz core clock after reset until
board-specific init-reset code sets up the PLL and enables a
faster JTAg clock.)
- Parport speed controls don't actually work (tops out at about
1 MHz on typical HW).
- In general, speed controls need to live in board.cfg files (or
sometimes target.cfg files), not interface.cfg ...

Previous patch somehow made GCC lose some of its cookies;
work around, zero-init that struct.

This patch includes partial support for these new JTAG adapters.
More complete support will require updates to the libftdi code,
for EEPROM access.

This patch adds basic autoprobing support for the JTAG scan chains
which cooperate. To use, you can invoke OpenOCD with just:
- interface spec: "-f interface/...cfg"
- possibly with "-c 'reset_config ...'" for SRST/TRST
- possibly with "-c 'jtag_khz ...'" for the JTAG clock
Then set up config files matching the reported TAPs. It doesn't
declare targets ... just TAPs. So facilities above the JTAG and
SVF/XSVF levels won't be available without a real config; this is
almost purely a way to generate diagnostics.
Autoprobe was successful with most boards I tested, except ones
incorporating C55x DSPs (which don't cooperate with this scheme
for IR length autodetection). Here's what one multi-TAP chip
reported, with the "Warn:" prefixes removed:
clock speed 500 kHz
There are no enabled taps. AUTO PROBING MIGHT NOT WORK!!
AUTO auto0.tap - use "jtag newtap auto0 tap -expected-id 0x2b900f0f ..."
AUTO auto1.tap - use "jtag newtap auto1 tap -expected-id 0x07926001 ..."
AUTO auto2.tap - use "jtag newtap auto2 tap -expected-id 0x0b73b02f ..."
AUTO auto0.tap - use "... -irlen 4"
AUTO auto1.tap - use "... -irlen 4"
AUTO auto2.tap - use "... -irlen 6"
no gdb ports allocated as no target has been specified
The patch tweaks IR setup a bit, so we can represent TAPs with
undeclared IR length.

Some cosmetic cleanup, and switch to a single table mapping
between state names and symbols (vs two routines which only
share that state with difficulty).
Get rid of TAP_NUM_STATES, and some related knowledge about
how TAP numbers are assigned. Later on, this will help us
get rid of more such hardwired knowlege.

- Use the name mappings all the other code uses:
+ name-to-state ... needed to add one special case
+ state-to-name
- Improve various diagnostics:
+ don't complain about a "valid" state when the issue
is actually that it must be "stable"
+ say which command was affected
- Misc:
+ make more private data and code be static
+ use public DIM() not private dimof()
+ shorten the affected lines
Re the mappings, this means we're more generous in inputs we
accept, since case won't matter. Also our output diagnostics
will be a smidgeon more informative, saying "RUN/IDLE" not
just "IDLE" (emphasizing that there can be side effects).

XSVF improvements:
- Layer parts of XSVF directly over SVF, calling svf_add_statemove()
instead of expecting jtag_add_statemove() to conform to the SVF/XSVF
requirements (which it doesn't).
This should improve XSTATE handling a lot; it removes most users of
jtag_add_statemove(), and the comments about how it should really do
what svf_add_statemove() does.
- Update XSTATE logic to be a closer match to the XSVF spec. The main
open issue here is (still) that this implementation doesn't know how
to build and submit paths from single-state transitions ... but now
it will report that error case.
- Update the User's Guide to mention the two utility scripts for
working with XSVF, and to mention the five extension opcodes.
Handling of state transition paths is, overall, still a mess. I think
they should all be specified as paths not unlike SVF uses, and compiled
to the bitstrings later ... so that we can actually make sense of the
paths. (And see the extra clocks, detours through RUN, etc.)
