Reverse engineered from USB logs. I never touched that programmer nor
did I ever see the associated software.
Disabled by default until it is complete. The driver needs to be hooked
up to the SPI core before it will do anything besides init and
diagnostics.

I successfully reverse engineered all commands, but some are still
somewhat magic.
Logs from "flashrom -p dediprog -V" are appreciated.

Probe and read should work, erase/write is expected to explode.
The programmer will set voltage to 0 on exit.

Thanks a lot to Stefan Reinauer and Patrick Georgi for providing USB
logs and for testing the result.

This is not just for fun. We hit a real bug on BSD with the outl macros.
The macro variable tmp collided with the tmp from outer scope.

second revision, now also taking care of inb/inw/inl. While that shadowing
did not introduce bugs (yet), of course it breaks the build on BSD when
-Wshadow is enabled.

And rename them accordingly. For now, main() just calls cli_classic(),
but alternative frontends can be switched in main().
Annotate remaining help texts with CLI dependency inside flashrom.c with
a FIXME comment.

Now people can go and create different frontends and be happy. Please
note that any other frontend will have to sort of duplicate the probing
code in cli_classic.c. Refactoring that part of the code is possible,
but not easy because we still want to print instructive help messages
for users.

Some programmers (most notably FT2232SPI) use fallback_* and noop_*,
but those functions lived inside internal.c and were unavailable if no
PCI-based programmers were compiled in.

Libpci is no longer required to build flashrom and will not be checked
for if no PCI code is needed for the selected programmers.
libftdi is no longer checked for if FT2232 support is not selected.

With this patch, it is possible to build on pretty much every OS out
there (including Windows) without altering the Makefile.
Some gcc versions may need a CFLAGS override for a warning in
dummyflasher.c, though.

Make various pieces of code conditional on support for internal
programming. Code shared between PCI device programmers and onboard
programming is now conditional as well.

It is now possible to build only with dummy support:
make CONFIG_INTERNAL=no CONFIG_NIC3COM=no CONFIG_SATASII=no
CONFIG_DRKAISER=no CONFIG_SERPROG=no CONFIG_FT2232SPI=no

This allows building for a specific use case only, and it also
facilitates porting to a new architecture because it is possible to
focus on highlevel code only.

Note: Either internal or dummy programmer needs to be compiled in due to
the current behaviour of always picking a default programmer if -p is
not specified. Picking an arbitrary external programmer as default  
wouldn't make sense.

Build and runtime tested in all 1024 possible build combinations. The
only failures are by design as mentioned above.

The code should work on Linux/*BSD/MacOSX and relies on the serial code
implementation in serial.c. Support for additional platforms (Windows)
will have to be added to serial.c for this to work. For tests without a
Bus Pirate (or with non-functional serial code) it is possible to
#define FAKE_COMMUNICATION in buspirate_spi.c.
Thanks to Sean Nelson for the SPI mode settings code. I tweaked it a bit
to make configuration from a commandline easier should anybody want that
feature.

So far, the only case where libz is needed is when a library (libpci)
pulls in libz and even then it only happens if libpci is available in a
static version only and said static version has libz requirements.

Check for libpci separately and don't require libz if it isn't needed.

The new option is '-p gfxnvidia', rest of the interface is as usual.

I tested a successful identify and read on a "RIVA TNT2 Model 64/Model 64 Pro"
card for now, erase and write did NOT work properly so far!

Please do not attempt to write/erase cards yet, unless you can recover!

In addition to the NVIDIA handling code it was required to call
programmer_shutdown() in a lot more places, otherwise the graphics card
will be disabled in the init function, but never enabled again as the
shutdown function is not called.
The shutdown handling may be changed to use atexit() later.

Example make commandline if you want only internal programmers:

Of course, all of the CONFIG_* symbols can be mixed and matched as

will check if the headers are available and skip it otherwise.

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.
