- Mixing uninitialized and initialized local variables leads to
confusion.
- ft2232_spi error cases should have gotten some error handling, and
that's the reason the curly braces were there.
- Fixing typos/wording in some places would have been nice given that
those places were touched anyway.

Also, indentation fixes, e.g. due to conversion to msg_*, use ARRAY_SIZE
where possible, wrap overly long line, etc.
Compile-tested. There should be no functional changes.

This patch attempts to resolve some programmer shutdown ordering issues
by having the programmer init functions register shutdown callbacks explicitly
wherever it makes most sense. Before, assumptions were made that could lead to
the internal programmer's state changing before the external programmer could be
shut down properly. Now, each programmer cleans up after itself and (hopefully)
performs each operation in the correct order.
As a side-effect, this patch gives us a better usage model for reverse
operations such as rpci_* and rmmio_*. In the long-run, this should make
reversing the initialization process easier to understand, less tedious, and
less error-prone.
In short, this patch does the following:
- Registers a shutdown callback during initialization for each programmer.
- Kills the .shutdown function pointer from programmer_entry struct. Also,
make most shutdown functions static.
- Adds a few minor clean-ups and corrections (e.g. missing physunmap() calls).

Remove the array spi_programmer, replace it by dynamic registration
instead. Also initially start with no busses supported, and switch to
the default non-SPI only for the internal programmer.
Also this patch changes the initialization for the buses_supported variable
from "everything-except-SPI" to "nothing". All programmers have to set the
bus type on their own, and this enables register_spi_programmer to just add
the SPI both for on-board SPI interfaces (where the internal programmer
already detected the other bus types), as well as for external programmers
(where we have the default "none").

Implement all Dediprog commands found in USB traces, even if their
purpose is not yet known.
Annotate unknown commands with info about the call sequence they are
embedded in and the firmware version of the log.
Add a new shutdown command for firmware 5.x (of which Stefan thinks it's
"switch the Pass light on" hence it is called late in the game)

Please note that the write speedup only applies to chips which have SPI
page write (i.e. chips using spi_chip_write_256).
This is a quick fix for write speed until I get around to implementing
full bulk SPI write support.

Should result in native speed for plain read and erase.
Should result in a measurable speedup for writes due to a fast verify.
Packet size is 512 bytes. Depending on your USB hardware and the
Dediprog firmware version, this may not work at all. That said, it
worked on the hardware we tested.
Add lots of error checking where it was missing before.
Thanks to Richard A. Smith, Mathias Krause and David Hendricks for
testing multiple iterations of this patch.

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

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.

unistd.h was only used to get a definition of NULL in all files. Add our
own NULL #define and remove unistd.h from flash.h
stdio.h has no place in flash.h, it should be included only in files
which really need it.
Add #include statements in individual .c files where needed.
Replace a few printf with msg_* to eliminate the need for stdio.h.

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.
