Provide new helper proc that can set up either an SWD or JTAG DAP
based on the transport which is in use -- mostly for SWJ-DP.
Also update some SWJ-DP based chips/targets to use it. The goal
is making SWD-vs-JTAG transparent in most places. SWJ-DP based chips
really need this flexible configuration to cope with debug adapters
that support different transports, without needing new target configs
for each transport or adapter.
For JTAG-DP, callers will use "jtag newtap" directly, as today; only
one chip-level transport option exists.
For SW-DP (e.g. LPC1[13]xx or EFM32, they'll use "swd newdap" directly
(part of an upcoming SWD transport patch). Again, only one transport
option exists, so hard-wiring is appropriate there.

When usng gdb pipes we need to keep openocd output at a minimum,
otherwise the gdb stdin will overflow and fail.
Make the calls to gdb_port and log_output synchronous to stop this.

commit 50d5441e2a615fb2c44b41a777e4373901f7a2e6 caused
native windows build to fail.
Firstly this patch fixes the build issue, but it also disables support
for named pipes under Windows. Windows does not support posix named
pipes.
A cross-platfom access layer will need creating before support can be
enabled again.

Stick with the name "gdb_port" even if this command

depending on whether the connection is over a socket
or pipe, the read is done differently.
pipes can return -1 when writing 0 bytes, make 0 byte
writes a successful no-op. 0 byte writes falls out
naturally of tcl server code.

There is an explicit command "log_output" that can
be used to redirect log output to a file, no need
for a hack in the first place.
Before enabling pipes, use "log_output foo" to redirect
log output to the "foo" files.

by using ctrl-z instead of line end, multi-line tcl scripts
can be handled.
Testing: send ctrl-z a couple of times to make telnet enter the
mode where it sends ctrl-z unencoded.
Programs that talk to the tcl_server can send ctrl-z to
indicate end of tcl-let to be executed without having
to worry about telnet protocols.

Hi everyone (again),
Watchpoints on xscale are quirky, so I thought a little explanation in the
user's manual was warranted.

Hi everyone,
A while back I sent in a patch that adds support for watchpoint lengths greater
than four on xscale. It's been working well, until the other day, when it
caused an unexpected debug exception. Looking into this I realized there is a
case where it breaks: when the length arg is greater than the base address.
This is a consequence of the way the hardware works. Don't see a work-around,
so I added code to xscale_add_watchpoint() to check for and disallow this
combination.
Some more detail... xscale watchpoint hardware does not support a length
directly. Instead, a mask value can be specified (not to be confused with the
optional mask arg to the wp command, which xscale does not support). Any bits
set in the mask are ignored when the watchpoint hardware compares the access
address to the watchpoint address. So as long as the length is a power of two,
setting the mask to length-1 effectively specifies the length. Or so I thought,
until I realized that if the length exceeds the base address, *all* bits of the
base address are ignored by the comaparator, and the watchpoint range
effectively becomes 0 .. length.
Questions, comments, criticisms gratefully received.
Thanks,
Mike

Hi everyone,
Added more LOG_ERROR messsages to watchpoint and breakpoint code, given that the
infrastructure no longer interprets returned error codes. Also changed
existing LOG_INFO and LOG_WARNING to LOG_ERROR for cases where an error is
returned.
Note that the check of the target state is superflous, since the infrastruture
code currently checks this before calling target code. Is this being
reconsidered as well? Also, should we stop returning anything other than
ERROR_OK and ERROR_FAIL?
Comments gratefully received.
Thanks,
Mike

Hi everyone,
Version 2 of this patch. Code added to breakpoints.c was removed from previous
patch, and item 3 added, per discussion with Øyvind regarding error reporting.
Item 4 added, which I just noticed.
I tried to use a software breakpoint in thumb code on the xscale for the first
time recently, and was surprised to find that it didn't work. The result was
this patch, which does four things:
1): fix trivial cut-n-paste error that caused thumb breakpoints to not work
2): call xscale_set_breakpoint() from xscale_add_breakpoint()
3): log error on data abort in xscale_write_memory()
4): fixed incorrect error code returned by xscale_set_breakpoint() when no
breakpoint register is available; added comment
Item 2 not only makes the xscale breakpoint code consistent with other targets,
but also alerts the user immediately if an error occurs when writing the
breakpoint instruction to target memory (previously, xscale_set_breakpoint() was
not called until execution resumed). Also, calling xscale_breakpoint_set() as
part of the call chain starting with handle_bp_command() and propagating the
return status back up the chain avoids the situation where OpenOCD "thinks" the
breakpoint is set when in reality an error ocurred.
Item 3 provides a helpful message for a common reason for failure to set sw
breakpoint.
This was thoroughly tested, mindful of the fact that breakpoint management is
somewhat dicey during single-stepping.
Comments and criticisms of course gratefully received.
Mike
