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.

Move that function to udelay.c and compile internal.c only if really
needed. physmap.c is only needed if the programmer is internal or a PCI
card. Make its compilation conditional.

Add a generic programmer list output function to be used by alternative
frontends. The interface between main() and doit is a hack and should
get a clean design, but for now it serves the purpose of shortening
main() by 120 lines. The rest of main() needs to be refactored a bit
more before moving main() away.

Only done for VT8237R (possibly needed for VT8237 too), VT8235 does
not need this (even if the original bios does so: Asus A7V8X-MX SE,

We could run it after chipset enable, but it definitely has to happen
before board enable because the board enable usually accesses the
SuperI/O. With this patch, it is possible to add a struct superio to the
board enable table for more accurate matching in case subsystem IDs are
ambiguous. This patch focuses on the generic infrastructure aspect and
on support for IT8712F/IT8716F.

Thanks go to Adrian Glaubitz and Ward Vandewege for testing.

If the JEDEC Toggle Bit algorithm needs more than 2^20 loops, it is a
good sign we should have used delays between toggle bit reads.

Tell the user about this. 2^20 loops need roughly a second depending on
flash bus speed. One reason for excessive loops can be a slow operation
like erase.

The Winbond W39V040C requires a 50 ms delay between toggle bit reads
during erase according to the datasheet. Turns out a 2 ms delay is
sufficient. Use a safety factor of 4 and default all erase operations
to 8 ms delay between toggle reads. This is short enough not to have
a substantial negative impact on erase times, and should improve
reliability.

This patch addresses the excessive toggle behaviour (observed on some
non-Winbond chips) and the toggle delay requirement (Winbond W39V040C).

This is a leftover from soyo SY-6BA+III code that turned out to be

This patch is only the first step, but it hopefully will make working
with the code and especially porting to new platforms easier.

Subsequent patches should move #includes for the newly created files
hwaccess.h and chipdrivers.h from flash.h to the files which need them.
Programmers should live in a separate header file as well.

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.

Tighten up board id match table in preparation of upcoming matching
changes.

Some boards are deliberately broken so that we will receive reports
or can remove support later (for instance, for agami aruma, which,
probably is no longer available in the wild).

* Acorp 6A815EPD: make autodetectable.
* Agami Aruma: remove bogus subsystem ids. Due to lacking secondary
  main id, this match will break soon.
* GIGABYTE GA-2761GXDK: Add secondary main id. Subsystem ids are not
  possible as they are all copies of the main ids. Will still require
  -m.
* GIGABYTE GA-M57SLI-S4: add full set of subsystem ids. Will keep
  match name for coreboot name matching.
* GIGABYTE GA-M61P-S3: Add secondary main id. Remove name match.
  Probably has good subsystem ids, but no info was found. So
  deliberately broken match.
* GIGABYTE GA-MA790FX-DQ6: pointless name match.
* IBM x3455: add full ids, remove name match.
* Kontron 986LCD-M: remove full id match as it is bogus. Kontron is
  an embedded vendor and does not bother with subsystem ids, so
  make this board name match only.
* MSI MS-6590 (KT4 Ultra): remove name match.
* MSI MS-7135 (K8N Neo3): add full id set, keep name match for
  coreboot.
* VIA EPIA-N/NL: remove name match.
* VIA PC3500G: remove name match.

The deleted function in en29f002a.c is reintroduced as
write_by_byte_jedec in jedec.c as it contains no chip-specific
instructions. It is not yet used in other chip drivers, as key addresses
(0x2AAA/0x5555) are often specified with less bits. After crosschecking
datasheets, most of the fixmes can probably be resolved as indicated in
them, causing significant code reduction.

The common JEDEC code for bytewise programming does not program 0xFF
at all. The chips that had a dedicated bytewise flash function which
has been changed to write_jedec_1 thus changed flashing behaviour
and the "write" test flag has been removed. This applies to: AMD
Am29F002BB/Am29F002NBB AMD Am29F002BT/Am29F002NBT (TEST_OK_PREW before)
AMIC A29002B AMIC A29002T (TEST_OK_PREW before) EON EN29F002(A)(N)B EON

 we probably should match all

same.
If anybody has contacts at Intel and can check, I'd be happy to add the
rest of the IDs.
