This patch adds support for FTDI FT2232-based USB programmers by using the FTDI hardware MPSSE engine. This patch is for SPI programmable parts only.

There are a few additions to the config file:

- programmer type "avrftdi"

- keyword "nbuff" for specifying the pins which need to be switched off (low, 0) when the output buffer is enabled (nOE).

- keywords "vid" and "pid" for USB PID/VID combination of the programmer

The patch supports baud rate (bit rate) selection either through the config file or as command line options. The pinout is bound only for the first three pins (SCK, MISO, MOSI), other pins may be chosen freely between pin numbers 3-11.

The patch uses libftdi, no D2XX support, yet.

The patch has been tested on OS X Leopard and Ubuntu 7.04 (with the autotools patch on both platforms). Tested programming hardware includes Olimex ARM-USB-OCD and Amontec JTAGkey. The only target tested is ATmega8L.

This patch is based on work by Hannes Weisbach.
