+@section Gerrit Review System
+
+All changes in the OpenOCD Git repository go through the web-based Gerrit
+Code Review System:
+
+@uref{http://openocd.zylin.com/}
+
+After a one-time registration and repository setup, anyone can push commits
+from their local Git repository directly into Gerrit.
+All users and developers are encouraged to review, test, discuss and vote
+for changes in Gerrit. The feedback provides the basis for a maintainer to
+eventually submit the change to the main Git repository.
+
+The @file{HACKING} file, also available as the Patch Guide in the Doxygen
+Developer Manual, contains basic information about how to connect a
+repository to Gerrit, prepare and push patches. Patch authors are expected to
+maintain their changes while they're in Gerrit, respond to feedback and if
+necessary rework and push improved versions of the change.

@section OpenOCD Developer Mailing List
The OpenOCD Developer Mailing List provides the primary means of
@uref{https://lists.sourceforge.net/mailman/listinfo/openocd-devel}
-Discuss and submit patches to this list.
-The @file{HACKING} file contains basic information about how

@deffn {Config Command} {cmsis_dap_vid_pid} [vid pid]+
The vendor ID and product ID of the CMSIS-DAP device. If not specified
-known default values are used.
+the driver will attempt to auto detect the CMSIS-DAP device.
Currently, up to eight [@var{vid}, @var{pid}] pairs may be given, e.g.

+Some nrf51-specific commands are defined:

+@deffn Command {nrf51 mass_erase}
+Erases the contents of the code memory and user information

-@deffn Command reg [(number|name) [value]]
+@deffn Command reg [(number|name) [(value|'force')]]
Access a single register by @var{number} or by its @var{name}.
The target must generally be halted before access to CPU core
registers is allowed. Depending on the hardware, some other
are flagged as such.
@emph{With number/name}: display that register's value.
+Use @var{force} argument to read directly from the target,
+bypassing any internal cache.
@emph{With both number/name and value}: set register's value.
Writes may be held in a writeback cache internal to OpenOCD,
