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.

The message printing code greatly exceed the 80 character limit. I can
reformat it on request to obey the limit.
Intended behaviour:
on untested boards an explanation of that status is printed and the board
enable code is not run, unless the option "boardenable=force" has been
passed to the internal programmer.

Still fallout of adding "-Wshadow". Missed the ht1000 one
(chipset_enable is not compied on Windows where we had the collision
with "byte" last time) and the other occurrence is newly introduced.
Old libpci defines a global symbol called "byte" too.

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.

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.

Linking in support for the internal programmer doesn't make sense if you
only need hardware (ioport, memory) access.
Note: This patch was created by "svn cp internal.c hwaccess.c" and then
removing stuff from both files. That's why you can't apply the patch
as-is before running the svn cp.

converted the majority of flash chips to sector erase.

This megapatch rewrites substantial parts of ICH SPI to actually do
what the SPI layer wants instead of its own weird idea about commands
(running unrequested commands, running modified commands). Besides that,
there is a fair share of cleanups as well.
- Add JEDEC_EWSR (Enable Write Status Register) to default commands. -
Mark a no longer used opcode/preopcode table as unused. - Declare all
commands as non-atomic/standalone by default. The ICH SPI driver has
no business executing commands (preopcodes) automatically if they were
not requested. - Automatically adjust preopcode/opcode pairings (like
WREN+ERASE) based on what the SPI layer requested. The ICH SPI driver
has no business executing altered opcode pairs as it sees fit. - Fix
incomplete initialization in the case of a locked down chipset. Leaving
the first 4 opcodes with uninitialized pairings had unpredictable
results. - switch() exists for a reason. Nested if() checking on the
same variable is an interesting style. - Actually check if the requested
readcnt/writecnt for a command is supported by the hardware instead
of delivering corrupt/incomplete commands and data. - If a command
has unsupported readlen/writelen, complain loudly to the user. - Use
find_opcode instead of open-coding the same stuff in a dozen variations.
- Introduce infrastructure for updating the command set of unlocked
chipsets on the fly.

This should take care of picky Linux kernels which do not allow uncached
mappings to cached areas. Handle mapping failure gracefully (no forced
exit()) if the caller specifies it.
Such cached areas which can handle mapping failure are DMI tables and
coreboot tables. On failure we just ignore those tables. That is not
perfect, but a lot better than aborting flashrom due to an error in
nonessential functionality.
This should fix flashrom on a sizable number of machines where it
currently aborts early.
Yes, I could have exploited a Linux kernel bug to "solve" this, but
relying on such bugs is not exactly the best idea.

Add this information to the new field in the board-enable table. We match the
board via two sets of PCI IDs. However, as we don't need a board-enable
function for this board (it works out of the box; well, at least if you remove
the JP9 jumper on the board), change the code to allow NULL as value for
the board-enable function. There will likely be more boards in the future where
we want to record a maximum decode size but which don't need a board-enable.
This is hardware-tested on the GIGABYTE GA-7ZM by successfully writing a 512KB
image of random bytes to a chip in this board.

Extend sst28sf040 to include chip and sector functions for block_eraser.
Extend sst49lfxxxc to include chip, sector, block erasers functions for
block_erasers. Extend sst_fwhub to include chip and sector functions for
block_erasers. Add copyrights to changed files. Killed erase_sst_fwhub.
Killed erase_49lfxxxc. NULL A/A mux mode full chip erasers. Ignore block
locks in erase/write. Change comments from "PP mode" to "A/A mux mode"

If a board is not uniquely identifiable by PCI device/subsystem IDs, a
string can be specified to be looked for (case-sensitive, substring or
anchored) for now in one of the following DMI items in addition to matching
the PCI IDs:
- System Manufacturer
- System Product Name
- System Version
- Baseboard Manufacturer
- Baseboard Product Name
- Baseboard Version
Strings are anchored re-like (^ at the beginning, $ at the end), but
there are no plans to support full regular expressions and matched to any
of the mentioned fields.
The match is only made if DMI info is available and the string matches.
If no DMI info is available and the PCI IDs match, a warning is printed
as the board can not be autodetected.
It's still open to discussion whether we add an DMI override switch to
specify a string that will definitely match, and whether this switch is
only used if no DMI is available or whether it overrides or augments DMI
data.
DMI data is currently read using dmidecode. This tool is available for
all major platforms except MacOS X. I heard that there also is a MacOS X
version of dmidecode, but didn't investigate that.
