+/**
+ * @file
+ * JTAG adapters based on the FT2232 full and high speed USB parts are
+ * popular low cost JTAG debug solutions. Many FT2232 based JTAG adapters
+ * are discrete, but development boards may integrate them as alternatives
+ * to more capable (and expensive) third party JTAG pods.
+ *
+ * JTAG uses only one of the two communications channels ("MPSSE engines")
+ * on these devices. Adapters based on FT4232 parts have four ports/channels
+ * (A/B/C/D), instead of just two (A/B).
+ *
+ * Especially on development boards integrating one of these chips (as
+ * opposed to discrete pods/dongles), the additional channels can be used
+ * for a variety of purposes, but OpenOCD only uses one channel at a time.
+ *
+ * - As a USB-to-serial adapter for the target's console UART ...
+ * which may be able to support ROM boot loaders that load initial
+ * firmware images to flash (or SRAM).
+ *
+ * - On systems which support ARM's SWD in addition to JTAG, or instead
+ * of it, that second port can be used for reading SWV/SWO trace data.
+ *
+ * - Additional JTAG links, e.g. to a CPLD or * FPGA.
+ *
+ * FT2232 based JTAG adapters are "dumb" not "smart", because most JTAG
+ * request/response interactions involve round trips over the USB link.
+ * A "smart" JTAG adapter has intelligence close to the scan chain, so it
+ * can for example poll quickly for a status change (usually taking on the
+ * order of microseconds not milliseconds) before beginning a queued
+ * transaction which require the previous one to have completed.
+ *
+ * There are dozens of adapters of this type, differing in details which
+ * this driver needs to understand. Those "layout" details are required
+ * as part of FT2232 driver configuration.
+ *
+ * This code uses information contained in the MPSSE specification which was
* found here:
* http://www.ftdichip.com/Documents/AppNotes/AN2232C-01_MPSSE_Cmnd.pdf
* Hereafter this is called the "MPSSE Spec".
*
* The datasheet for the ftdichip.com's FT2232D part is here:
* http://www.ftdichip.com/Documents/DataSheets/DS_FT2232D.pdf
+ *
+ * Also note the issue with code 0x4b (clock data to TMS) noted in
+ * http://developer.intra2net.com/mailarchive/html/libftdi/2009/msg00292.html
+ * which can affect longer JTAG state paths.
