Antonio Borneo 8c1d518232 arm_adi_v5: add option 'root' to 'dap info' command
On ADIv6 the system root ROM table is found by reading the DAP DP
registers BASEPTR0 and BASEPTR1.

Add option 'root' to the commands 'dap info' to let it retrieve
the system root ROM table's AP from DAP DP, then use such AP for
following dump.

Antonio Borneo 3f4bc6ce7f adiv6: use struct adiv5_ap->ap_num to contain the AP base address
ADIv5 DAP can only have 256 AP, while ADIv6 can provide till
2**40 (1,099,511,627,776) AP per DAP.

Reuse the field ap_num in struct adiv5_ap, currently used on ADIv5
to hold the ADIv5 AP number (apsel), to contain the ADIv6 AP base
address.

Convert struct adiv5_ap->ap_num to 64 bit and initialize it to
DP_APSEL_INVALID for unused AP.
Restrict dap_find_get_ap() to ADIv5 only. To be enhanced.
On ADIv6, let dap_get_ap() return an already allocated AP, or
allocate and return an unused AP.
Add function is_ap_num_valid() and use it.

Kevin Burke 62058c0a32 adi_v5_jtag: extend memaccess_tck to every AP access
ADIv5 reports:
	Accessing AP registers or debug resources in connected
	device through an AP can be subjected to other variable
	response delays in the system. A debugger that can adapt
	to these delays and avoid wasting WAIT scans operates more
	efficiently and provides higher maximum data throughput.

The existing code in OpenOCD uses extra tck only for accessing
resources through an AP.

Extend the use of extra tck also for accessing an AP register.

Antonio Borneo 35a503b08d arm_adi_v5: add ap refcount and add get/put around ap use
While an ADIv5 DAP can only have 256 AP, ADIv6 can provide till
2**40 (1,099,511,627,776) AP per DAP.
The actual trivial code implementation for ADIv5 (that uses an
array of 256 ap in the struct adiv5_dap) cannot be extended as-is
to handle ADIv6.

The simple array of 256 AP can be reused as a dynamic storage for
ADIv6 ap:
- the ADIv5 AP number is replaced by the ADIv6 base address;
- the index of the array (equal to ADIv5 AP number) has no link to
  any ADIv6 property;
- the ADIv6 base_address has to be searched in the array of AP.

The 256 elements in the AP array should be enough for any device
available today. In future it can be easily increased, if needed.

To efficiently use the 256 elements in the AP array, the code
should associate one element of the array to an ADIv6 AP (through
the AP base address), then cancel the association when the AP is
not anymore needed. This is important to avoid saturating the AP
array while exploring the device through 'dap apreg' commands.

Add a reference counter in the struct adiv5_ap to track how many
times the struct has been associated with the same base address.
Introduce the function dap_get_ap() to associate and return the
struct, and dap_put_ap() to release the struct. For the moment the
code covers ADIv5 only, so the association is through the index.
Use the two functions above and dap_find_get_ap() throughout the
code.
Check the return value of dap_get_ap(). It is always not NULL in
the current ADIv5-only implementation, but can be NULL for ADIv6
when there are no more available AP in the array.
Instrument dap_queue_ap_read() and dap_queue_ap_write() to log an
error message if the AP has reference counter zero, meaning that
the AP has not been 'get' yet. This helps identifying AP used
without get/put, e.g. code missed by this patch, or merged later.
Instrument dap_cleanup_all() to log an error message if an AP has
reference counter not zero at openocd exit, meaning that the AP
has not been 'put' yet.

Thomas Hebb 830d70bfc6 tcl/interface/ftdi: Add config for Tigard board
Tigard[1] is an FT2232H-based development tool designed for ease of use
with many different protocols and targets. It includes a JTAG header
wired to channel B, with labeled pins for the four required signals as
well as nTRST and nSRST, which are connected through an output buffer to
BDBUS4 and BDBUS5 respectively.

Add an interface config for Tigard. I wrote it by referencing the Tigard
schematic and tested it by debugging a couple of RISC-V development
boards.

Antonio Borneo cc75aa37c5 openocd: add post-init and pre-shutdown helpers
It is a common requirement to automatically execute some command
after "init".
This can be achieved, either in scripts or through OpenOCD command
line, by explicitly calling "init" followed by the commands.
But this approach fails if the request for post-init commands is
spread across configuration files; only one of the files can split
pre-init and post-init status by calling "init".
The common workaround is to "rename" the command "init" and
replace it with a TCL proc that calls the original "init" and the
post-init commands. E.g. in Zephyr script [1].

To simplify and formalize the post-init execution, use a TCL list
that contains the list of commands to be executed. Every script
can contribute adding new commands, e.g. using "lappend".

In the same way, formalize the pre-shutdown execution with a TCL
list of user commands to be executed before OpenOCD exit.

Document them and add trivial examples.

Drop from documentation the suggestion to rename "shutdown".

Antonio Borneo 99293ebd15 aarch64: don't wait for smp targets halted in deassert reset
The function target_type::deassert_reset() is called for every
target after reset is deasserted. If the target fails to get
halted, we log a warning and issue a halt request for the target
itself.

Current code calls the generic target_halt() that:
- extends the halt to all the targets in the SMP node;
- waits for targets to halt.
This breaks the logic of running target_type::deassert_reset()
per target. Plus, waiting for targets to halt delays the call of
target_type::deassert_reset() for the next targets.

Replace the call to target_halt() with the aarch64 specific
function to halt the single target. Pass the parameter HALT_LAZY
to prevent the wait for target halted.
Similar solution is already implemented for cortex_a.

Antonio Borneo a47d1f1b79 arm_adi_v5: add support for 64bit Class 0x9 ROM tables
Arm documentation does not explicitly report the order of the two
32bit words that compose the 64bit value. But both ADIv5 and ADIv6
specify that only little-endian is supported (ADIv5.2 obsoletes
the big-endian support). This change reads the 64bit value in
little-endian.

Detect the 64bit content and use it.

Antonio Borneo 613f1c6abb arm_adi_v5: let dap_lookup_cs_component() to get AP dbgbase
Simplify the code in cortex_a and aarch64 by moving the call to
dap_get_debugbase() inside dap_lookup_cs_component().

This has the further effects:
- dap_get_debugbase() is not referenced outside arm_adi_v5.c and
  becomes static;
- dap_lookup_cs_component() looses one parameter;
- the coreid parameter 'idx' is passed as value;
- the caller in aarch64 don't have and don't print the irrelevant
  value of AP register APID;
- fixes the debug message in the caller in aarch64 to print the
  coreid value instead of always zero.
