This patch adds support for a new SPI programmer, based on the FT2232H/4232H chip from FTDI

Browse Source 
FTDI support is autodetected during compilation.

Paul writes:
There are certainly possible improvements: The code has hard-coded
values for which interface of the ftdi chip to use (interface B was
chosen because libftdi seems to have trouble with A right now), what
clock rate use for the SPI interface (I've been running at 30Mhz, but
the patch sets it to 10Mhz), and possibly others. I think this means
that per-programmer options might be a good idea at some point.

Carl-Daniel writes:
There is one additional FIXME comment in the code, but AFAICS that
problem is not solvable with current libftdi.

Corresponding to flashrom svn r598.
