The following write granularities exist according to my datasheet
survey: - 1 bit. Each bit can be cleared individually. - 1 byte. A byte
can be written once. Further writes to an already written byte cause
the contents to be either undefined or to stay unchanged. - 128 bytes.
If less than 128 bytes are written, the rest will be erased. Each write
to a 128-byte region will trigger an automatic erase before anything is
written. Very uncommon behaviour. - 256 bytes. If less than 256 bytes
are written, the contents of the unwritten bytes are undefined.

Note that chips with default 256-byte writes, which keep the original
contents for unwritten bytes, have a granularity of 1 byte.

Handle 1-bit, 1-byte and 256-byte write granularity.

This patch puts the description of the different programmers into a
separate section of the manpage instead of having them one after the
other without visual structuring in the description of "-p". It is
made as a preparation of a man-page patch that adds the background
of board enables into flashrom.8 that would really blow up the OPTIONS
section.

The only differences in content are:
 - The parameter for serprog is mandatory, not optional
 - Default behaviour of it87spi (using BIOS-set I/O address) is mentioned.
 - Default speed of buspiratespi is mentioned.

Some programmers want to run certain functions during programmer
shutdown, but the function choice depends on the code path taken
during programmer init. Rather than rebuilding the whole init logic in
the shutdown function, it is now possible to register functions for
execution on programmer shutdown. The behaviour is similar to atexit(),
but the registered functions will be run on programmer shutdown instead
of on exit and the functions will be called with a void * argument
that is specified on registration. Registered functions must have
the prototype void function(void *); and will be executed in reverse
registration order directly before calling the programmer-specific
shutdown() function. It is recommended to have shutdown() only disable
programmer/hardware access and leave all code path sensitive shutdown to
functions registered with register_shutdown().

The most prominent use case is resetting the EC after flashing on
laptops.

Note: There are quite a few code paths in flashrom which proceed to
terminate flashrom without any programmer shutdown. Those code paths
will not get the benefit of register_shutdown() and they should be
changed wherever possible.

Huge thanks to Michael Karcher for reverse engineering the MCP67 chipset
and writing a spec. Due to this, we were able to use the chinese wall
technique for 100% clean room reverse engineering.

This patch doesn't touch any of the new registers, it only reads them.
Assuming that read has no side effects, this patch is a no-op and safe.

We need "flashrom -V" output from all post-MCP55 (nForce 5) chipset
boards. Please indicate if your board uses SPI flash or LPC flash (if
you know it). Note: That output is only helpful if it is created with
patched flashrom and if is from the first run of flashrom after a cold
boot (reset or Ctrl-Alt-Del is not sufficient). There is a pattern based
on which we can probably detect which flash type is present on the
board.

Thanks to Alessandro Polverini for testing earlier iterations of this
patch.

Note: The MCP67 should work. I guessed that the other recent Nvidia
chipsets would work in a similar way, and created a simplified
do-nothing catchall chipset enable function which dumps some info and
instructs the user to send more info.
