The Flash Configuration Field on Kinetis devices requires protection
because it is located in program flash space (at 0x400) and writing
an improper data to it may permanently lock the device. Even an erased
flash sector containing FCF engages security lock (not permanent one)
on the next reset or power cycle.
'kinetis fcf_source protection' mode was introduced in the change #3562.
Flash driver in this mode sets FCF immediately after sector erase to
prevent unintentional security lock. To do so the driver needs to know
FCF values before flash image data is actually processed. Flash
protection bits are available in bank structure, FOPT can be set by
'kinetis fopt' command and securing device by FSEC is not supported.
Nevertheless an inexperienced user flashed the device using an image
with FCF values different from those set in OpenOCD config and
concluded programming did not work as some verify errors showed.
This change tries to write maximum possible from image data
retaining FCF protection.
Check FCF in programmed data and report if some field differs from
values set by OpenOCD flash block protection and 'kinetis fopt' command.
Warn user about verify errors caused by FCF protection.
On devices with ECC flash (K26, K66 and KV5x) it is impossible to change
already programmed FCF - it would result in an ECC error. As FCF was
written just after erase in 'kinetis fcf_source protection' mode
the warning issued during flash write is the only possible action.
On non-ECC flash devices use cumulative flash programming to
set FCF values requested in programmed image data.
Use FSEC from programmed data only if it does not request a secure
mode. Device can be secured only in 'kinetis fcf_source write' mode.
Use FOPT from programmed data if its value was not configured
in OpenOCD config by 'kinetis fopt' command.

This commit contains a rewrite of the jtagspi protocol and covers both
changes in the jtagspi.c openocd driver and the bscan_spi
(xilinx_bscan_spi) proxy bitstreams. The changes are as follows:
1. Always perform IR scan to ensure proper clearing of BYPASSed DRs.
2. Insert alignment cycles for all BYPASSed TAPs:
The previous logic was erroneous. The delay in clock cyles from a bit
written to the jtag interface to a bit read by the jtag interface is:
* The number of BYPASSed TAPs before this (jtagspi) tap
* The length of the jtagspi data register (1)
* The number of BYPASSed TAPs before this one.
I.e. it is just the number of enabled TAPs. This also gets rid of the
configuration parameter DR_LENGTH.
3. Use marker bit to start spi transfer
If there are TAPs ahead of this one on the JTAG chain, and we are in
DR-SHIFT, there will be old bits toggled through first before the first
valid bit destined for the flash.
This delays the begin of the JTAGSPI transaction until the first high bit.
4. New jtagspi protocol
A JTAGSPI transfer now consists of:
* an arbitrary number of 0 bits (from BYPASS registers in front of the
JTAG2SPI DR)
* a marker bit (1) indicating the start of the JTAG2SPI transaction
* 32 bits (big endian) describing the length of the SPI transaction
* a number of SPI clock cycles (corresponding to 3.) with CS_N asserted
* an arbitrary number of cycles (to shift MISO/TDO data through
subsequent BYPASS registers)
5. xilinx_bscan_spi: clean up, add ultrascale
This is tested on the following configurations:
* KC705: XC7K325T
* Sayma AMC: XCKU040
* Sayma AMC + RTM): XCKU040 + XC7A15T, a board with integrated FTDI JTAG
adapter, SCANSTA JTAG router, a Xilinx Ultrascale XCKU040 and a Xilinx
Artix 7 15T. https://github.com/m-labs/sinara/wiki/Sayma

When listening on port 0, the system will assign a random open port. We
use this to run multiple OpenOCD instances against multiple simulators
as part of regression testing. This mechanism means the various test
instances don't have to coordinate to ensure they don't reuse any ports.
The required changes are minimal:
1. Don't increment the port number when it's 0.
2. Print out which port was assigned by the system.

mem_ap_setup_tar() writes to MEM_AP_REG_TAR if requested TAR value
changed or CSW_ADDRINC_... is currently active.
However if an autoincremented access has been issued and autoinc
switched off in CSW afterwards, TAR does not get updated.
The change introduces mem_ap_update_tar_cache() which is called
after queuing of any access to MEM_AP_REG_DRW. It simulates
TAR increment to keep tar_value in sync with MEM_AP.
Crossing tar autoincrement block boundary invalidates cached value.
mem_ap_write() and mem_ap_read() do not check tar autoincrement
block boundary, mem_ap_setup_tar() is called before each transfer instead.
dap_invalidate_cache() is introduced to ensure invalidation
of all cached values during dap_dp_init() and swd_connect()
