Previously boards in the wiki were tagged either as working or as known
bad. But we added support to various boards via board enables that were
then never tested because the owners have not reported back. This can
now be tagged with NT and is shown appropriately.

Also, the underlying data structure indicating state was converted from
macros to an enum while preserving original integer values and is used
for programmers and chipsets too.

Similar to modules using the opaque programmer framework (e.g. ICH Hardware
Sequencing) this uses a template struct flashchip element in flashchips.c with
a special probe function that fills the obtained values into that struct.

This allows yet unknown SPI chips to be supported (read, erase, write) almost
as if it was already added to flashchips.c.

Some flash chips contain OTP memory that we cannot read or write (yet). This
prohibits us from cloning them, hence warn the user if we detect it. Not all
variations of the tagged chips contain OTP memory. They are often only
enabled on request or have there own ordering numbers. There is usually no
way to distinguish them. Because this is a supposedly seldomly used feature
the warning is shown in with dbg verbosity.

The manpage is extended to describe the backgrounds a bit.

All programmer types (Parallel, SPI, Opaque) now register themselves
into a generic programmer list and probing is now programmer-centric
instead of chip-centric.
Registering multiple SPI/... masters at the same time is now possible
without any problems. Handling multiple flash chips is still unchanged,
but now we have the infrastructure to deal with "dual BIOS" and "one
flash behind southbridge and one flash behind EC" sanely.

A nice side effect is that this patch kills quite a few global variables
and improves the situation for libflashrom.

Hint for developers:
struct {spi,par,opaque}_programmer now have a void *data pointer to
store any additional programmer-specific data, e.g. hardware
configuration info.

Note:
flashrom -f -c FOO -r forced_read.bin
does not work anymore. We have to find an architecturally clean way to
solve this.

Struct flashchip is used only for the flashchips array and for
operations which do not access hardware, e.g. printing a list of
supported flash chips.

struct flashctx (flash context) contains all data available in
struct flashchip, but it also contains runtime information like
mapping addresses. struct flashctx is expected to grow additional
members over time, a prime candidate being programmer info.
struct flashctx contains all of struct flashchip with identical
member layout, but struct flashctx has additional members at the end.

The separation between struct flashchip/flashctx shrinks the memory
requirement of the big flashchips array and allows future extension
of flashctx without having to worry about bloat.

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).

TODO: Remove forward declaration of serprog_shutdown() (added to simplify diff)

This will allow flashrom to skip erase of already-erased blocks and to
skip write of blocks which already have the wanted contents.

Avoid emergency messages by checking if the chip contents after a failed
write operation (erase/write) are unchanged.

Keep the emergency messages after a failed pure erase. That part is
debatable because if someone wants erase, he pretty sure doesn't care
about the flash contents anymore.

Please note that this introduces additional overhead of a full chip read
before write. This is frowned upon by people with slow programmers. A
followup patch will make this configurable.
