Erase functions are no longer called from chip drivers and thus their

There was one line break added too much in the previous commit, sorry.
the probing functions need to output at least one '\n' for satisfactory output.
that means even in error cases they have to do that.
OTOH they should not output a sequence of "\n\n" because
it would distort the verbose probing output with empty lines.

Add lock printing for Atmel AT26DF081A, AT26DF161, AT26DF161A,
AT26DF321.

Move Atmel AT25*/AT26* lock related functions originally added in r1115
from spi25.c to at25.c.

For SPI chips the lock printing was handled by one common function, but
sharing a common function which only is a big switch() statement doesn't
make sense, especially if we can define lock printing functions per
flash chip anyway.

The printlock function pointer in struct flashchip is used to print
status register and locking information, and serves as replacement for
implicit status register and lock printing during probe. That code will
later be changed to store locking info in a machine- accessible data
structure so flashrom can handle locked regions...

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").

This patch reduces the stack usage by declaring 'const' stack variables
as 'static const' so they end up in the .rodata section instead of being
copied from there to the stack for every invocation of the corresponding
function.

As a plus we end up in having a smaller binary as the "copy from .rodata
to stack" code isn't emitted by the compiler any more (roughly -100
bytes).

Flashrom had an implicit erase-on-write for most flash chip and
programmer drivers, but it was not entirely consistent.

Some drivers had their own hand-rolled partial update functionality
which made handling partial updates from generic code impossible.

Move implicit erase out of chip drivers, and kill some dead erase
functions at the same time. A full chip erase is now performed in the
generic code for all flash chips on write, and after that the whole chip
is written.

SPI RES is the most unreliable way to identify chips because it only
returns a 1-byte ID for most chips.

For every given ID out there, probably a dozen incompatible flash
chips match it. We already refuse to identify a chip with RES if that
chip responds to RDID (3 bytes, good match), and with this patch we
additionally refuse RES if the chip responds to REMS (2 bytes, still a
good match). This increases matching accuracy a lot.

Besides that, the RDID/REMS response checking has been cleaned up for
better readability.

Some mingw declares a global identifier "byte", causing -Werror -Wshadow
to break compilation. This patch renames all identifiers called "byte".

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.

Example usage:
flashrom -p buspiratespi:spispeed=2.6MHz,dev=/dev/foo
flashrom -p buspiratespi:dev=/dev/foo,spispeed=2.6M

Refactor programmer option parsing (this allows cleanups in other
programmers as well).

Increase SPI read size from 8 to 12 bytes (current single-transaction
limit of the Bus Pirate raw SPI protocol).

Add Bus Pirate to the list of programmers supporting 4 byte RDID.

Add Bus Pirate syntax to the man page.

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.
