Antonio Borneo 7819834ace target: fix build with jimtcl 0.79
In jimtcl 0.80 the prototype of Jim_DictPairs() has changed.
The only code in OpenOCD that uses Jim_DictPairs() has been merged
recently and it only uses the current jimtcl syntax.

To allow compiling OpenOCD master branch with older versions of
jimtcl, detect the version of jimtcl and use the appropriate
syntax.

Antonio Borneo b4f8d99c8d smp: deprecate legacy SMP core switching support
The deprecation was already in the documentation since v0.11.0
through commit 85ba2dc4c6 ("rtos/hwthread: add hardware-thread
pseudo rtos") but OpenOCD was not informing the user printing a
runtime message.

Remove the deprecated method from the documentation and print a
deprecated message at runtime.
There is no reliable way to print the same message in GDB console,
so we have to rely on user noticing it in the OpenOCD log.
Target is to remove the functionality after v0.12.0.

Antonio Borneo 2cafa8be73 semihosting: fix mode flags for local host open()
Commit dbbac5f11d ("semihosting: use open mode flags from GDB,
not from sys/stat.h") fixes the conversion of the mode flags from
ARM semihosting encoding for SEMIHOSTING_SYS_OPEN to GDB mapping
for open().
Doing this, it breaks the conversion to local host's OS mapping
for open().

Split the conversion array to one for GDB and one for local host.
The local host conversion array is taken directly from the old
code.

Marc Schink fb43f1ff4e target: Rework 'set' variable of break-/watchpoints
The 'set' variable name suggests a boolean data type which determines
whether a breakpoint (or watchpoint) is active. However, it is also
used to store the number of the breakpoint.

This encoding leads to inconsistent value assignments: boolean and
integer values are mixed. Also, associated hardware comparator
numbers, which are usually numbered from 0, cannot be used directly.
An additional offset is required to store the comparator numbers.

In order to make the code more readable and the value assignment more
consistent, change the variable name to 'is_set', its data type to 'bool'
and introduce a dedicated variable for the break-/watchpoint
number.

In order to make the review easier, the data types of various related
variables (e.g. number of breakpoints) are not changed.

While at it, fix a few coding style issues.

This command permits the usage of a TCP port to perform debug and stdio
operations:
 - debug : READC, WRITEC and WRITE0
 - stdio : READ, WRITE

This will permit the separation of semihosting message from OpenOCD log,
and separate semihosting messages per core.

syntax: arm semihosting_redirect (disable | tcp <port> [debug|stdio|all])

this allows to select which operations to be performed via TCP (debug,
stdio or all (default)).

Note: for stdio operations, only I/O from/to ':tt' file descriptors are
redirected.

Marc Schink 38183dc856 target/tcl: Add 'read_memory' and 'write_memory'
These functions are meant as replacement for 'mem2array' and
'array2mem'.

The main benefits of these new functions are:

 * They do not use Tcl arrays but lists which makes it easier
   to parse (generate) the data. See the Python Tcl RPC code
   in contrib as a negative example.

 * They do not operate on Tcl variables but instead return (accept)
   the Tcl list directly. This makes the C and Tcl code base
   smaller and cleaner.

 * The code is slightly more performant when reading / writing
   large amount of data. Tested with a simple Python Tcl RPC
   benchmark.

Enabling a portion (0x100 - 0x107) of the user defined semihosting
operation number range (0x100 - 0x1FF) to be processed with the help of
the existing target event mechanism, to implement a general-purpose Tcl
interface for the target available on the host, via semihosting
interface.

Example usage:
- The user configures a Tcl command as a callback for one of the newly
	defined events (semihosting-user-cmd-0x10X) in the configuration
	file.
- The target can make a semihosting call with <opnum>, passing optional
	parameters for the call.

If there is no callback registered to the user defined operation number,
nothing happens.

Example usage: Configure RTT automatically with the exact, linked
control block location from target.

Tomas Vanek 33fa237b2f target/cortex_m: minor refactoring in cortex_m_store_core_reg_u32()
Unlike cortex_m_load_core_reg_u32() storing core register uses
the same code pattern around DHCSR read as offered by the convenience
helper cortex_m_read_dhcsr_atomic_sticky().

Use the helper.

Bohdan Tymkiv 71ca3a1349 target/arm_jtag.h: fix wrong comparison in arm_jtag_set_instr
Change [1] introduced a regression that results in comparison
in arm_jtag_set_instr() to be always true if the length of the
IR register is not 8 bit. The value on the left side
of the != operator contains only tap->ir_length number of
bits while value on the right is full 8-bit instruction code.

This forces OpenOCD to update the JTAG IR register on each
transaction even if the instruction in the JTAG IR register
is correct. This causes noticeable performance degradation,
especially with slow JTAG adapters.

Antonio Borneo 68ec9d2175 adi_v5_swd: add jtag-to-swd through dormant
ARM IHI 0031A does not support SWJ-DP, so no switch between JTAG
and SWD is considered.
ARM IHI 0031B is not publicly available and it's reported as
"Confidential Beta" in the history list in following doc versions.
From ARM IHI 0031C the direct switch between JTAG and SWD is
already deprecated in favor of passing through dormant mode. With
no access to IHI 0031B we haven't info if any device strictly
requires the direct switch.

OpenOCD implements only the deprecated direct switch, so changing
it could cause regression on devices that do not implement dormant
mode.
Plus, not all the adapters support dormant mode.

Nevertheless there are already target devices that only allow
entering in SWD by passing through dormant.

Let the code try both method, alternating one tentative with the
deprecated legacy direct switch, then another tentative passing
through dormant, and repeat till timeout.
This would work on any device that don't support dormant, on new
devices that require switch through dormant and will work with
adapters that don't support dormant.

Tomas Vanek d203399787 target/adi_v5_swd: add support for SWD multidrop
Based on Graham Sanderson's http://review.openocd.org/4935

Unlike Graham Sanderson's version this patch does not add
any multidrop specific queuing.

Multidrop SWD is handled mostly by the same code as single SWD,
just a selection sequence is prepended to a SWD operation
as needed.

This is a minimal working implementation without checking for
configuration errors (mixing multidrop and non multidrop DPs,
multiple use of the same selection id etc...).

Multidrop switching likely demands changes in the adapter code.
