This is for targets where flash controller has reverse endianness
compared to target.  For these, the 'bus_swap' parameter can be given to the
CFI driver, which will cause command CFI commands to be written with
bytes swapped.  This is only for x16 CFI flash.

Due to signal propagation delays, sampling TDO on rising TCK can become

Matthias Welwarsky 5373085b4d adiv5: introduce optional dap_sync() function
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.

Matthias Welwarsky a185eaad9d adi_v5_jtag: implement DAP WAIT support
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.

Peter Lawrence 2f131d3c30 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.

Matthew Campbell 37252b2313 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.

Matthias Welwarsky 464f7005bb arm_debug: optimize DP and AP reads over JTAG
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().

Matthias Welwarsky 45b897873d cortex_a: select APB-AP as the default AP
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

each call through the AP/DAP pointer.

Consolidate the cache of the SELECT fields into one single field caching

Move the mandatory dap_ap_select() call into the dap_queue_ap_read/write

This avoids the need for dap_ap_select() and the notion of a "current" AP

Andreas Fritiofson e7d165f3db arm_adi_v5: Remove all cases of "restoring" previous dap_ap_select()
All AP operations should select the AP to use before calling it so
there's no point in restoring the previous value afterwards.

The explicit call to dap_ap_select() before all AP operations should be
moved into dap_queue_ap_read/write() which then would have to take the
AP as an argument instead of the DAP.

call sites to use the appropriate one.
