Add a --list-supported-wiki / -z option which outputs the currently
supported flash chips (and their status, size, and type), chipsets (plus
status), mainboards (plus status), and external PCI devices usable as
programmer to stdout.

This allows for very easy pasting into the http://coreboot.org/flashrom


page, so we can keep that page up-to-date without much hassle.

The list of boards is mostly new (known good ones which don't need
write-enable code, and known-bad ones) and also lists URLs to the
vendor's mainboard pages.

FTDI support is autodetected during compilation.

Paul writes:
There are certainly possible improvements: The code has hard-coded
values for which interface of the ftdi chip to use (interface B was
chosen because libftdi seems to have trouble with A right now), what
clock rate use for the SPI interface (I've been running at 30Mhz, but
the patch sets it to 10Mhz), and possibly others. I think this means
that per-programmer options might be a good idea at some point.

Carl-Daniel writes:
There is one additional FIXME comment in the code, but AFAICS that
problem is not solvable with current libftdi.

That means you can tell flashrom to read exactly bytes 12345-56789

And even when it checks if the erase worked, the result of that check is
often ignored.

Convert all erase functions and actually check return codes
almost everywhere.
Check inside all erase_* routines if erase worked, not outside.
erase_sector_jedec and erase_block_jedec have changed prototypes to
enable erase checking.

This was partly due to a design problem in the abstraction layer.

There should be exactly two different functions for reading SPI chips:
- memory mapped reads
- SPI command reads.

Each of them should be contained in a separate function, optionally
taking parameters where needed.

This patch solves the problems mentioned above, shortens the code and
makes the code logic a lot more obvious.

Since open-coding the min() function leads to errors, include it in this
patch as well.

In particular, it should no longer be necessary to patch the makefile
for hassle-free compilation.

The targets are:
make export
make tarball
Both preserve svn revisions and the exported tree does not depend on
subversion in any way or shape.

Documentation for this feature has been added to README.

We need this for five reasons:
1. Packagers currently have to patch flashrom source to compile it on
systems without subversion. We should make it easier for them.
2. Snapshot tarballs currently have a .svn 1.5 directory included but
this will cause errors for users with older svn 1.4. Not requiring
subversion for snapshot compilation is best.
3. Since packagers seldom the svn revision in their fixup patches, some
packages out there have incorrect or no revision, only major version
numbers.
4. Releasing a new version of flashrom needs too many changes to the
makefile which have to be reverted instantly after the release. That is
unnecessary churn.
5. Making a release is easy with the change. Update the major version,
then run "make tarball".

Not only does this violate the principle of least surprise, it also

Add chip_{read,write}n to the external flasher infrastructure which
read/write n bytes at once.

Fix a few places where the code used memcpy/memcmp although that is
strictly impossible with external flashers.
Place a FIXME in the layout.c code because usage is not totally clear
and needs to be fixed to support external flashers.

As a nice side benefit, we get a noticeable speedup for builtin flash
reading which is now a memcpy() of the full flash area instead of a
series of single-byte reads.
