Remove since long deprecated ft2232 driver
Purge all legacy interface configurations so there's no more confusion
over which one to use.
Also remove doc/INSTALL.txt which mentions ft2232 but otherwise just
duplicates what INSTALL says.

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. - */ - -#ifdef HAVE_CONFIG_H -#include "config.h" -#endif - -/* project specific includes */ -#include <jtag/interface.h> -#include <transport/transport.h> -#include <helper/time_support.h> - -#if IS_CYGWIN == 1 -#include <windows.h> -#endif - -#include <assert.h> - -#if (BUILD_FT2232_FTD2XX == 1 && BUILD_FT2232_LIBFTDI == 1) -#error "BUILD_FT2232_FTD2XX && BUILD_FT2232_LIBFTDI are mutually exclusive" -#elif (BUILD_FT2232_FTD2XX != 1 && BUILD_FT2232_LIBFTDI != 1) -#error "BUILD_FT2232_FTD2XX || BUILD_FT2232_LIBFTDI must be chosen" -#endif - -/* FT2232 access library includes */ -#if BUILD_FT2232_FTD2XX == 1 -#include <ftd2xx.h> -#include "ftd2xx_common.h" - -enum ftdi_interface { - INTERFACE_ANY = 0, - INTERFACE_A = 1, - INTERFACE_B = 2, - INTERFACE_C = 3, - INTERFACE_D = 4 -}; - -#elif BUILD_FT2232_LIBFTDI == 1 -#include <ftdi.h> -#endif - -/* max TCK for the high speed devices 30000 kHz */ -#define FTDI_x232H_MAX_TCK 30000 -/* max TCK for the full speed devices 6000 kHz */ -#define FTDI_2232C_MAX_TCK 6000 -/* this speed value tells that RTCK is requested */ -#define RTCK_SPEED -1 - -/* - * On my Athlon XP 1900+ EHCI host with FT2232H JTAG dongle I get read timeout - * errors with a retry count of 100.
