e466f389a9 jtag/drivers: replace perror() with LOG_ERROR()
The function perror() sends the output to stderr, but OpenOCD
cannot intercept such output to send it to the log.

Replace all occurrences of perror() with LOG_ERROR(), but keeping
the same output format of perror().

The replacement is done automatically through:
	sed -i 's/perror("\([^":]*\)[: ]*")/LOG_ERROR("\1: %s", strerror(errno))/' src/jtag/drivers/*.c

964680ecff bitbang: split jtag and swd operations
The split in OpenOCD between SWD and JTAG has been already fully
implemented. The bitbang driver still keeps a single API write()
to drive the output lines.

Introduce a new SWD specific API swd_write().
Move the existing SWD bitbang drivers to the new API by extracting
the available conditional implementation.
Cleanup some function prototype.
Remove the now unused global swd_mode, handled implicitly.
Rename bitbang_exchange() as bitbang_swd_exchange() to track its
scope for SWD only.

49232a80d2 bitbang: remove superfluous switch between jtag and swd
The SWD framework already takes care of switching between JTAG and
SWD by calling driver's switch_seq() in swd_connect() and in
swd_quit(); there is no need for the driver to force the switch
again.

Remove the extra switch between jtag and swd.

efd1d64222 adapter: switch from struct jtag_interface to adapter_driver
To reorganize the adapters code, introduce an adapter_driver
struct that contains all the adapter generic part, while
keeping in two separate struct the specific API jtag_ops and
swd_ops.
Move the allocation of *adapter_driver from the JTAG-specific
file core.c to the more adapter-specific file adapter.c
While splitting the old jtag_interface for every driver, put
the fields in the same order as in the struct declaration so
we keep a consistent code across all the drivers.

While other transport specific API could/would be added as
separate ops, nothing is done here for HLA.

8850eb8f2c swd: get rid of jtag queue to assert/deassert srst
The transport SWD uses the JTAG queue to assert/deassert the
system reset srst. This is the major inconsistency that has to be
removed to properly split JTAG and SWD.

Introduce a new driver API, reset(), to controls both the signals
trst and srst in the driver, skipping the JTAG queue. Put the new
API in struct jtag_interface, even if in this patch it's used for
SWD only; the goal is to get it reused by the other transports.

Add the implementation of the API in all the drivers that
implement SWD. Such implementation is almost the same of the old
code in JTAG queue.

Create a wrapper adapter_system_reset() to use the new API and
remove the SWD specific swd_add_reset(). In the wrapper replace
jtag_add_sleep() with jtag_sleep(), because the former uses the
JTAG queue too.
Rename the old jtag_add_reset() as legacy_jtag_add_reset() with
the target to remove it when all drivers would be ported to the
new reset API. Create a new jtag_add_reset() that calls the
legacy function for drivers still on the old reset API.

Use the new API also on JTAG transport for the drivers that can
support both SWD and JTAG.

For the moment, do not modify the implementation of JTAG-only
drivers, which will continue using the usual method. This should
be cleaned-up in future commits.

6cb5ba6f11 helper/command: change prototype of command_print/command_print_sameline
To prepare for handling TCL return values consistently, all calls
to command_print/command_print_sameline should switch to CMD as
first parameter.

Change prototype of command_print() and command_print_sameline()
to pass CMD instead of CMD_CTX.
Since the first parameter is currently not used, the change can be
done though scripts without manual coding.
This patch is created using the command:
	sed -i PATTERN $(find src/ doc/ -type f)
with all the following patters:
	's/\(command_print(cmd\)->ctx,/\1,/'
	's/\(command_print(CMD\)_CTX,/\1,/'
	's/\(command_print(struct command_\)context \*context,/\1invocation *cmd,/'
	's/\(command_print_sameline(cmd\)->ctx,/\1,/'
	's/\(command_print_sameline(CMD\)_CTX,/\1,/'
	's/\(command_print_sameline(struct command_\)context \*context,/\1invocation *cmd,/'

This change is inspired by http://openocd.zylin.com/1815 from Paul
Fertser but is now done through scripting.

f9056d222c drivers/imx_gpio: fix usage messages
The notation "(tck tms tdi tdo)* " is incorrect, because it means the
quadruple of gpio can be repeated on the command-line.
The correct syntax of the command requires instead to provide either
all the four gpio numbers (in order to set the values) or to pass an
empty command-line (to dump the values previously set).

Change the .usage field to "[tck tms tdi tdo]".
Change similarly the corresponding .usage field for SWD command.
Add the .usage field for the commands that individually set each gpio
or gpio property.
Dump the previously set values when commands imx_gpio_speed_coeffs or
imx_gpio_peripheral_base are executed with empty command-line.

64f1f7b1c1 Add read buffer to bitbang, improving performance.
Previously for every bit scanned OpenOCD would write the bit, wait for
that bit to be scanned, and then read the result. This involves at least
2 context switches. Most of the time the next bit scanned does not
depend on the last bit we read, so with a buffer we now write a bunch of
bits to be scanned all at once, and then we wait for them all to be
scanned and have a result.

This reduces the time for one testcase where OpenOCD connects to a
simulator from 12.30s to 5.35s!

Running all our tests went from 13m13s to 3m55s.

83c67b7ac7 imx_gpio: add mmap based jtag interface for IMX processors
For some targets (like nrf51) sysfs driver is too slow. This
patch implements memory maped driver for IMX processors.
Mostly based on bcm2835gpio. Tested on imx6ul CPU. However, it should
work on any NXP IMX CPU.
