It used to set all states to halted, but that's not right for harts that
are now unavailable. (It might be possible to call poll() at the right
time instead of duplicating some of its code, but I didn't see an easy
way to do that. The real requirement is that target->state is set to
TARGET_UNAVAILABLE before TARGET_EVENT_HALTED is is sent in
halt_finish(), because that's what triggers hwthread_update_threads(),
which must know about unavailable harts so they can be hidden from gdb.

Indicate to the JTAG driver that it does not need
to read and return the DR register value after scanning the
JTAG chain.
riscv_batch_run(), calls jtag_add_dr_scan() to schedule a
DR scan operation. Eventually, this will result in the JTAG
driver performing a JTAG scan to write to or read from DR.
The decision on whether to write to and/or read from DR
register is determined by the second parameter to
jtag_add_dr_scan(), i.e. a "struct scan_field".
Of particular interest here is if
batch->fields[i]->in_value is not NULL, the JTAG developer
must return the DR value collected from the JTAG scan
operation.
When creating the DR scan operation instruction with
riscv_batch_add_dmi_write(), batch->fields[i]->in_value points
to a location in batch->data_in buffer,
meaning batch->field[i]->in_value is not NULL, and the JTAG
developer must therefore read and return the DR value collected.
The returning of the DR value is redundant in a write
operation.
This patch set batch->fields[i]->in_value to NULL to indicate
the DR value need not be returned. This allows the JTAG
developer to optimize away any code associated with returning
the DR value.
Normally, the extra work to return the DR value is negligible.
However, in one usecase it introduces significant delays
In this use case a JTAG driver forwards
all JTAG scan to a server on a network. If the server has to
return the DR value, it has to perform the JTAG scan before
replying to the JTAG driver, and only then the JTAG driver
can send the next JTAG scan operation. However, if there is
no need to return the DR value, the server can
acknowledge the JTAG operation request immediately,thus
signalling to the JTAG driver that it is free to send the next
JTAG scan operation. At the same time of receiving the second
JTAG operation the server will process the original JTAG scan.
This saves time and mitigates network delay. Also, not having
to include the DR value in resulting in smaller reply packet
from server to JTAG driver and save on network traffic.
This doubles download speeds to spike using remote bitbang.

This was used to track which hart a given operation must apply to. But
we already have a target associated with each operation, and from there
we can find the desired hart id. dm013_info_t already tracks
current_hartid (meaning which hart ID is currently selected by the DM).
This makes the code simpler to understand. Also it turns out we don't
need to make sure the correct hart ID is currently selected because
there are only a few real entry points.

This commit corrects the erase function for stm32f2x when dealing with
sectors in bank 2, for STM32F42x/43x devices with 1MB flash.
On STM32F42x/43x with 1MB flash in dual bank configuration, the sector
numbering is not consecutive. The last sector in bank 1 is number 7, and
the first sector in bank 2 is number 12.
The sector indices used by openocd, however, _are_ consecutive (0 to 15
in this case). The arguments "first" and "last" to stm32x_erase() are of

Since the two banks in dual bank mode have the same number of sectors, a
sector index in bank 2 is larger than or equal to half the total number

The third parameter of container_of() should point to the same member

It worked just because struct arm is the first member in

If you move arm member from the first place, OpenOCD fails heavily.

* target: ls1088a: Add service processor
Normally the service processor is not necessary for debugging. However,
if you are using the hard-coded RCW or your boot source is otherwise
corrupt, then the general purpose processors will never be released from
hold-off. This will cause GDB to become confused if it tries to attach,
since they will appear to be running arm32 processors. To deal with
this, we can release the CPUs manually with the BRRL register. This
register cannot be written to from the axi target, so we need to do it
from the service processor target. This involves halting the service
processor, modifying the register, and then resuming it again. We try
and determine what state the service processor was in to avoid resuming
it if it was already halted.
The reset vector for the general purpose processors is determined by the
boot logation pointer registers in the device configuration unit.
Normally these are set using pre-boot initialization commands, but if
they are not set then they default to 0. This will cause the CPU to
almost immediately hit an illegal instruction. This is fine because we
will almost certainly want to attach to the processor and load a program
anyway.
I considered adding this as an event handler for either gdb-attach or
reset-init. However, this command shouldn't be necessary most of the
time, and so I don't think we should run it automatically.

* board: Add NXP LS1088ARDB
This adds a board file for the NXP LS1088ARDB. This only covers the
"primary" JTAG header J55, and not the PCIe header (J91). The only
oddity is that the LS1088A and CPLD are muxed by adding/removing a
jumper from J48. Unfortunately, it doesn't look like OpenOCD supports
this CPLD beyond determining the irlen, so it's not very useful. Those
who are interested in experimenting can define CWTAP to access the CPLD,
but the default is to access the CPU.

* udev: fix permission for Ambiq Micro EVK's
Commit 68e204f1e9 ("udev: Add rules for Ambiq Micro EVK's.") was
initially proposed as http://openocd.zylin.com/3429/ then replaced
by http://openocd.zylin.com/3980/
The initial proposal was for file '99-openocd.rules', in which
MODE="664" was the norm.
After merge of http://openocd.zylin.com/2804/ the new udev rules
in '60-openocd.rules' switched to MODE="660", but the evolution of
the above patch missed this change.
Switch udev rules of Ambiq Micro EVK's to MODE="660" and uniform
them to the rest of the file.

There is a single reset API at adapter driver to assert/deassert

cause also trst to change value, hanging the SWD communication.
In SWD mode, ignore the value passed to trst.

* configure: drop macro 'AC_HEADER_TIME'
The macro AC_HEADER_TIME has been obsoleted by autoconf 2.70.
Not all systems provide 'sys/time.h', plus some old system didn't
allowed to include both 'time.h' and 'sys/time.h' because 'time.h'
was included by 'sys/time.h' and was not properly protected to
allow multiple inclusion.
The macro AC_HEADER_TIME helps to detect such odd case.
Nowadays all the systems properly protect 'time.h', so its safe to
unconditionally include 'time.h', even if it is also included by
'sys/time.h'.
The case of systems without 'sys/time.h' is already covered by
configure.ac through the directive
AC_CHECK_HEADERS([sys/time.h])
Remove the obsoleted autoconf macro and simplify the code by
including 'time.h' unconditionally and check HAVE_SYS_TIME_H to
include 'sys/time.h'.

invalidates the discovery on USB, even if it was successful.
Factor-out parts of the jlink_init into separate jlink_open_device
function, use that function to firstly discover and match USB
devices and, if matching device was not found on the USB bus and
serial number was specified, repeat discovery and matching via TCP.

This is a fix for an issue reported by Joe Stoy at:
https://sourceforge.net/p/openocd/mailman/message/37128537/
When clearing sbcs.sbbusyerror, preserve other bits in the sbcs
register that are needed for subsequent system bus transactions.
This lets a user see exactly what period of time was sampled, without
having to guess how much time the target was ignored in between bursts.

These are all the changes from https://github.com/riscv/riscv-openocd
(approximately 91dc0c0c) made just to src/target/riscv/*. Some of the
new code is disabled because it requires some other target-independent
changes which I didn't want to include here.
Built like this, OpenOCD passes:
* All single-RV32 tests against spike.
* All single-RV64 tests against spike.
* Enough HiFive1 tests. (I suspect the failures are due to the test
suite rotting.)
* Many dual-RV32 (-rtos hwthread) against spike.
* Many dual-RV64 (-rtos hwthread) against spike.
I suspect this is an overall improvement compared to what's in mainline
right now, and it gets me a lot closer to getting all the riscv-openocd
work upstreamed.

* riscv: work around buggy hart states during reset in some DMs
As described in the comment this change adds, the GD32VF103 DM reports
that the hart is in more than one state while it is resetting. Because
of this, the current code acknowledges resets before they actually
complete. This sometimes prevents havereset from getting cleared as
intended, leading to a spurious "Hart 0 unexpectedly reset!" message the
next time riscv_is_halted() gets called.
To work around this, check for the absence of the unavailable state
rather than the presence of the running or halted states. This behavior
is also arguably more true to the spec than what exists now: Section 3.2
states that "The system may take an arbitrarily long time to come out of
reset, as reported by allunavail, anyunavail."

* riscv: support custom reset-assert scripts
The reset-assert event is used, if present, to override the default
reset logic for ARM and MIPS cores. Do the same for RISC-V so that
devices with buggy ndmreset functionality (like GD32VF103) or
nonstandard reset sequences can specify the appropriate logic in Tcl.

* tcl/target: support GD32VF103 RISC-V MCU
The GD32VF103 is a low-cost 32-bit RISC-V microcontroller with
peripherals that are more-or-less compatible with the STM32F103 ARM
microcontroller. It is available on several low-cost dev boards, such as
the Sipeed Longan Nano, which is what I am testing on.
Add initial support for this chip, including a workaround for a buggy
ndmreset line (i.e. one that doesn't actually trigger a reset) in its
integrated debug module. Use the existing GD32VF103 flash driver that
was ported from the vendor's code in commit 48e40f3513 ("Add support
for GD32VF103 flash").

* tcl/target/gd32vf103: add main flash alias
The GD32VF103 creates an alias to either main flash or the bootloader at
0x0, depending on how it was booted. As such, we want to indicate to
debuggers that the memory at 0x0 is flash and so cannot support software
breakpoints. To do this, add an alias to the main flash in the config.
This isn't strictly accurate in the case where we're running the
bootloader, but it still suits our purpose of fixing breakpoint
behavior.

* Allocate RISC-V arch_info during target creation
* Ensured that target->arch_info is allocated as soon as the

* Add flexible selection of memory access methods, detection of aampostincrement.
New configuration command introduced: "riscv set_mem_access".
It allows to specify which RISC-V memory access methods (progbuf,
sysbus and/or abstract access) should be tried and in which order
of priority.
Command "riscv set_prefer_sba" is left and works in backward
compatible way, but is marked as deprecated.
First time abstract memory access is executed, it is tried with
set aampostincrement bit. If the abstract command fails or the
address is not incremented correctly, aampostincrement will not
be used for any subsequent accesses.

In a switch/case statement, a break placed after a goto or return
is never executed.
The script checkpatch available in Linux kernel v5.1 issues a
