target: improve robustness of reset command
Before this change jim_target_reset() checked examined state of a target
and failed without calling .assert_reset in particular target layer
(and without comprehensible warning to user).
Cortex-M target (which refuses access to DP under active SRST):
If connection is lost then reset process fails before asserting SRST
and connection with MCU is not restored.
This resulted in:
1) A lot of Cortex-M MCUs required use of reset button or cycling power
after firmware blocked SWD access somehow (sleep, misconfigured clock etc).
If firmware blocks SWD access early during initialization, a MCU could
become completely inaccessible by SWD.
2) If OpenOCD is (re)started and a MCU is in a broken state unresponsive
to SWD, reset command does not work even if it could help to restore communication.
Hopefully this scenario is not possible under full JTAG.
jim_target_reset() in target.c now does not check examined state
and delegates this task to a particular target. All targets have been checked
and xx_assert_reset() (or xx_deassert_reset()) procedures were changed
to check examined state if needed. Targets except arm11, cortex_a and cortex_m
just fail if target is not examined although it may be possible to use
at least hw reset. Left as TODO for developers familiar with these targets.
cortex_m_assert_reset(): memory access errors are stored
instead of immediate returning them to a higher level.
Errors from less important reads/writes are ignored.
Requested reset always leads to a configured action.
arm11_assert_reset() just asserts hw reset in case of not examined target.
cortex_a_assert_reset() works as usual in case of not examined target.

cortex_a: allow physical memory access through AHB-AP again
This feature is required for boards that use a programmatical way
to reset the cpu, like the TI Pandaboard with OMAP4. The board only
has a 14 pin JTAG header that doesn't feature SRST and is reset by
direct write to the PRM_RSTCTL register.
iMX6 can be reset through triggering the on-chip watchdog, but for these
methods to work reliably, access through the AHB-AP without interaction
with the CPU core is necessary.
This patch adds a 'ftdi_location' command to select an adapter by usb
bus number and port path.
This is helpful if you have a rack full of adapters in a testing or
manufacturing setup where the only constant is the physical usb bus
location of the adapter you want to address. Vid:Pid are not unique,
serial number _may_ be unique (and maybe not with embedded adapters) but
will change when a new target is plugged.

2) Doing the busy-wait in the loader merely reduced the time to 19 minutes.

getting us down to ~2 seconds for 8 KB and ~2.5 minutes for 1.1 MB.

dap_sync() executes all commands in the JTAG queue and then checks
if a WAIT condition happened inside the last batch. If yes, a recovery
is invoked. If not, processing continues without checking for
errors. This function should be called in long AP read or writes, e.g.
while uploading a new application binary, at intermediate points within
the transfer where the cost of flushing the JTAG queue and checking the
journal doesn't affect performance too much.
ADIv5 specifies that DP and AP accesses may generate a WAIT
response when the hardware is not able to complete a request for various
reasons in time before the next request is sent. Currently, the software
treats a WAIT response as a fatal error and aborts operation on the DAP.
This patch implements WAIT handling by keeping a journal of all
outstanding and completed accesses, including their response status.
At certain times (when dap_run() is called), the journal is inspected
for WAIT responses and all discarded accesses are replayed to complete
them. Special care is taken to not re-execute already successfully
completed operations.

ARM ADIv5: CoreSight ROM decode part number and designer id
The existing arm_adi_v5.c code decodes CoreSight peripherals based
on the part number field. However, these are specific to a
particular manufacturer (often ARM). The same part number from
two different manufacturers (distinct designer ids) should not
decode as the same CoreSight peripheral.
The Analog Devices ADSP-SC58x and ADSP-BF70x have peripherals that
overlap with existing OpenOCD decoding. The part number is the
same as existing OpenOCD decoding, but have a different JEP106 code.
Most, if not all, of the existing part number entries in
arm_adi_v5.c are probably specific to ARM. Change all entries
suspected to be designed by ARM to match only ARM's designer ID.
However, to preserve legacy behavior, existing non-ARM entries are
encoded with a wildcard so that they will behave in the same way as
the existing legacy code. It is desirable, however, to start
encoding the data with designer codes to avoid such ambiguity.
Revising the code to check both the part number and designer id
seemed to a warrant a const array lookup table instead of a
multi-tiered switch statement.
Also try to sync part identification IDs with relevant ARM docs.

AM335x: allow simultaneous debugging of A8 and M3 cores
This patch fixes the tap order so that it matches the actual jtag
chain when all taps are enabled. It also introduces a variable
DEFAULT_TAPS that can be set outside of this script, e.g. on the
command line, to specify which taps are to be enabled on init.
Lastly, a new debug target "am335x.m3" is added so that the Wakeup-M3
can be selected for debugging.

sysfsgpio: support broken gpio implementations
Change tests when reading from 'value' in sysfs from =='0' to !='1'.
This guards against broken sysfs GPIO implementations that return
non-zero for high rather than just '1' while still being clean and
correct code. Note that sysfs will never output a leading zero even
in a very broken implementation as that is covered in gpiolib.c, not
the offending driver.
Tested against broken Freescale kernel 3.14.38 on i.MX6SL.

On JTAG, all reads are pipelined. If you read a register, the result is not
delivered inside the request that issued the read, it is delivered in the
following request. The current code therefore issues a scan of the RDBUFF
register after each read. This adds a superfluous transaction after each
read.
This patch follows a strategy similar to what SWD already implements.
It also leverages that all JTAG reads are pipelined, i.e. the result
will be clocked out in the next JTAG data phase, no matter if it's
READ or WRITE. Therefore it's never necessary to explicitly read RDBUFF
other than for the very last READ before a dap_run().
Debug initialization blindly selects AP#0 as default, which is the AHB-AP
in many cases. This sets the default for target_read/write functions.
However, AHB-AP is the wrong choice, because it bypasses caches on read
and write and also makes some peripherals inaccessible (e.g. l2 outer
caches). This patch explicitely selects the APB-AP (debug_ap) as the
default.
Remove entirely the concept of a "selected" AP that has to be maintained
between calls. All the information the DAP ops need are now provided to
each call through the AP/DAP pointer.
Consolidate the cache of the SELECT fields into one single field caching
the entire register.
