11019a824d adi_v5: enforce check on AP number value
The AP number value is restricted in 8 bits unsigned by ADI-v5
specification. Nevertheless, an "invalid" value is used by
target cortex-m to force an automatic detection of the AP.

Replace magic numbers by using new macros for AP max number and
for the value of AP invalid.
Check the value passed through -ap-num flag during configuration.

e48690cb26 target/arm_adi_v5: allow commands apsel and apcsw during init phase
The current implementation of apsel cannot be executed during the
initialization phase because it queries the DAP AP to retrieve and
print the content of IDR register, and the query is only possible
later on during the exec phase.
But IDR information is already printed by the dedicated command
apid, making redundant printing it by apsel too.
Being unable to run apsel during initialization, makes also apcsw
command (that depends on apsel) not usable in such phase.

Modify the command apsel to only set the current AP, without making
any transfer to the (possibly not initialized yet) DAP. When run
without parameters, just print the current AP number.
Change mode to COMMAND_ANY to apsel and to apcsw.

For very low level debug or development around DAP, it is useful
to have direct access to DP registers.

Add command "dpreg" by mimic the syntax of the existing "apreg"
command:

0057c71ab6 target/arm_adi_v5: sync CSW and TAR cache on apreg write

Reuse the setup functions for CSW and TAR to write them.
Invalidate the cached value before the call to force the write, thus
keeping original apreg behaviour.

- clean up swd connect
- re-initialize DAP also on JTAG errors (e.g. after reset,

- update documentation

4553abf906 arm_adi_v5: fix wrong addressing after change of CSW_ADDRINC
Problem: If the same memory location is accessed alternatively
by MEM-AP banked data registers without autoincrement and by standard
autoincremented read/write, TAR register is not updated correctly.

How to replicate: On a Cortex-M issue
    mdw 0xe000edf0
multiple times. When poll is on (poll reads the same memory location)
only the first read is correct.
0xe000edf0: 01000000
0xe000edf0: 00000000
0xe000edf0: 20002640
0xe000edf0: 01000000
0xe000edf0: 00000000
0xe000edf0: 00000000

No problems with poll off.
0xe000edf0: 01000000
0xe000edf0: 01000000
0xe000edf0: 01000000

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()

Simplify by printing one component per call, instead of one complete ROM
Table per call. Print common information the same way for all components,
including ROM tables, because ROM tables (at least the top level) contain
useful information in their identification registers, such as the
manufacturer of the SoC.

Print component designer name using the JEP106 helper when available.

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.

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.

bfba15a898 adi_v5: Fix wrong ap value
Problem
dap->ap_current is register value, not field value.
it restores invalid ap when it calls dap_ap_select(dap, ap_old) later.

* assume the current ap is 1, dap->ap_current value would be (1 << 24).
ap_old = dap->ap_current;   <-- ap_old = 1<<24 = 0x1000000.
...
dap_ap_select(dap, ap_old); <-- select 0x1000000, not 1.
* All AP registers accessing fail afterwards.

One of the reproducible case(s): CORE residents in AP >= 1
  dap_lookup_cs_component() being used to find PE(*).
  In most cases, PE would be found in AP==0, hence the problem is hidden.
  When AP number is 1, dap->ap_current would have the value of 1<<24.
  Anyone get the AP value with dap->ap_current and resotre it later would
  select the wrong AP and all accessing later would fail.

  The ARM Versatile and/or FPGA would have better chance to provide this
  kind of environment that PE residents in AP>=1. As they have an 'umbrella'
  system at AP0, and main system at AP>=1.

  * PE: Processing Element. AKA Core. See ARM Glossary at
    http://infocenter.arm.com/help/topic/com.arm.doc.aeg0014g/ABCDEFGH.html

Fix
Use dap_ap_get_select() to get ap value.
a. Retrieve current ap value by calling dap_ap_get_select();
     src/flash/nor/kinetis.c
     src/target/arm_adi_v5.c

b. The code is correct (dap->ap_current >> 24), but it's better to use
   dap_ap_get_select() so everything could be synchronized.
