The default way of working is to have a single GDB attached to one
target, so OpenOCD accepts only one connection to the GDB port of
each targets and rejects any further connection.
There are some barely safe use cases in which it could get useful
having a second GDB connection to the same target.
One such use case is while using GDB as a 'non-intrusive memory
inspector', as explained in the OpenOCD documentation.
One GDB can be left running an infinite loop to dump some memory
area, or even analysing the content, while keeping a second GDB
ready for user interaction or spot memory check.
Add a target configure option to specify the maximum number of GDB
connections allowed for that target, keeping the default to 1.

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.

This driver provides support for Cadence JTAG BFM
The "jtag_dpi" driver implements a JTAG driver acting as a client for the
SystemVerilog Direct Programming Interface (DPI) for JTAG devices.
DPI allows OpenOCD to connect to the JTAG interface of a hardware model
written in SystemVerilog, for example, on an emulation model of
target hardware.
Tested on Ampere emulation with Altra and Altra Max models

Commit 87a4158acf ("drivers: xds110: Clean up command syntax and
documentation") does not follow the documentation structure that
lists the adapters in cpt 2 "Debug Adapter Hardware" then lists
the adapter commands in cpt 8.2 "Interface Drivers"; it puts all
in cpt 2.
While doing that, uses an incorrect texinfo syntax that causes the
following warnings at compile time:
doc/openocd.texi:543: warning: @deffn should only appear at the beginning of a line
doc/openocd.texi:547: warning: @deffn should only appear at the beginning of a line
doc/openocd.texi:552: warning: @deffn should only appear at the beginning of a line
Move the documentation of xds110 commands in the proper chapter
and fix the texinfo syntax.

TARGET_EVENT_RESUME_*.
This is an example of a concrete use case where having
these events is important:
In RISC-V processors without Debug Program Buffer, OpenOCD
cannot execute fence/fence.i when resuming or single-
stepping. With these events implemented, the user can
instead provide custom operations to achieve that same
effect prior to resuming the processor.

While installing git on Windows, the user is prompted by a dialog
"Configuring the line ending conversions" to select the value for
the git property "core.autocrlf". The default choice proposed by
the installer is "Checkout Windows-style, commit Unix-style line
endings", that corresponds to "core.autocrlf=true".
Even if the dialog provides technical explanation of the different
choices, most users will blindly accept the default proposal.
With "core.autocrlf=true" git will convert to DOS mode all the
text files during "clone" (so can be edited by any crap Windows
tool) and convert back to UNIX mode during "push" operation.
While this is safe enough for C and TCL files, it breaks the
texinfo files.
The trailing '@' character used for command continuation in
https://www.gnu.org/software/texinfo/manual/texinfo/html_node/Def-Cmd-Continuation-Lines.html
does not accept being followed by CR+LF (DOS mode), generating a
build error. Same error can be replicated on Linux by passing the
file doc/openocd.texi through "unix2dos" command.
Tentative to fix this has already been proposed in
http://openocd.zylin.com/5294http://openocd.zylin.com/5413
by breaking the command continuation syntax, which is a no go.
The correct fix would require to force/suggest all the Windows
users to get rid of the crap DOS mode, but this could have side
effects.
To workaround the issue, add a .gitattributes file in the doc
folder, specifying a local conversion attribute for the files .txt
and .texi in the doc folder and overriding the eventual incorrect
global value of "core.autocrlf" selected during installation.
The local attribute "text eol=lf" is equivalent to the global one
"core.autocrlf=input".
