only.

-Using FTDI's FTD2XX
--------------------
-
-The (closed source) FTDICHIP.COM solution is faster than libftdi on
-Windows. That is the motivation for supporting it even though its
-licensing restricts it to non-redistributable OpenOCD binaries, and it
-is not available for all operating systems used with OpenOCD. You may,
-however, build such copies for personal use.
-
-The FTDICHIP drivers come as either a (win32) ZIP file, or a (Linux)
-TAR.GZ file. You must unpack them ``some where'' convenient. As of this
-writing FTDICHIP does not supply means to install these files "in an
-appropriate place."
-
-You should use the following ./configure options to make use of
-FTD2XX:
-
-  --with-ftd2xx-win32-zipdir
-                          Where (CYGWIN/MINGW) the zip file from ftdichip.com
-                          was unpacked <default=search>
-  --with-ftd2xx-linux-tardir
-                          Where (Linux/Unix) the tar file from ftdichip.com
-                          was unpacked <default=search>
-  --with-ftd2xx-lib=(static|shared)
-                          Use static or shared ftd2xx libs (default is static)
-
-Remember, this library is binary-only, while OpenOCD is licenced
-according to GNU GPLv2 without any exceptions. That means that
-_distributing_ copies of OpenOCD built with the FTDI code would
-violate the OpenOCD licensing terms.
-
-Note that on Linux there is no good reason to use these FTDI binaries;
-they are no faster (on Linux) than libftdi, and cause licensing issues.
