Programmer specific functions are of absolutely no interest to any file
except those dealing with programmer specific actions (special SPI
commands and the generic core).

The new header structure is as follows (and yes, improvements are
possible):
flashchips.h  flash chip IDs
chipdrivers.h  chip-specific read/write/... functions
flash.h  common header for all stuff that doesn't fit elsewhere
hwaccess.h hardware access functions
programmer.h  programmer specific functions
coreboot_tables.h  header from coreboot, internal programmer only
spi.h SPI command definitions

Convert all PCI-based external programmers to use special little-endian
accessors for all MMIO regions of PCI devices. This patch does _not_
touch the internal programmer (which is PCI-based as well).

Huge thanks go to Misha Manulis who worked with me to create a first
version of this patch for the satasii programmer based on modification
of generic code.

Huge thanks also go to Segher Boessenkool for suggesting the pci_mmio_
prefix for the abstraction layer.

NOTE to package maintainers: With this patch, compilation and usage of
flashrom should be safe on x86, x86_64, MIPS (little and big endian) and
PowerPC (big endian).

The internal programmer is disabled on non-x86/x86_64 (but it
compiles). The atahpt, nic3com, nicnatsemi, nicrealtek and rayer_spi
can not be compiled on non-x86/x86_64 because port space I/O is
not (yet) supported. Please compile with default settings on
x86/x86_64 and with the following settings on all other architectures:
make CONFIG_NIC3COM=no CONFIG_NICREALTEK=no CONFIG_NICNATSEMI=no
CONFIG_RAYER_SPI=no

Use the BAR value returned by pcidev_init which automatically applies
the correct BAR mask for the drkaiser driver. Truncate flash chip
addresses to fit into the 128 kB memory window for drkaiser and pick the
same window size for gfxnvidia.

Uwe tested all operations successfully on a Dr. Kaiser card.

This led to wildly differing syntax for programmer parameters, and
it also voids pretty much every assumption you could make about
programmer_param. The latter is a problem for libflashrom.

Use extract_param everywhere, clean up related code and make it more
foolproof. Add two instances of exit(1) where we have no option to
return an error. Remove six instances of exit(1) where returning an
error was possible.

WARNING: This changes programmer parameter syntax for a few programmers!

Constify variables where possible.
Initialize programmer-related variables explicitly in programmer_init to
allow running programmer_init from a clean state after
programmer_shutdown.
Prohibit registering programmer shutdown functions before init or after
shutdown.
Kill some dead code.
Rename global variables with namespace-polluting names.
Use a previously unused locking helper function in sst49lfxxxc.c.

This is needed for libflashrom.

Effects on the binary size of flashrom are minimal (300 bytes
shrinkage), but the data section shrinks by 4384 bytes, and that's a
good thing if flashrom is operating in constrained envionments.

We don't need to duplicate OK and NT as PCI_OK and PCI_NT if the symbols
are already there (defined for the chipset enable table).

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.
