One of the problems is that --force had multiple meanings
- Force chip read by faking probe success.
- Force chip access even if the chip is bigger than max decode size for
the flash bus.
- Force erase even if erase is known bad.
- Force write even if write is known bad.
- Force writing even if cbtable tells us that this is the wrong image
for this board.
This patch cleans up --force usage:
- Remove any suggestions to use --force for probe/read from flashrom
output.
- Don't talk about "success" or "Found chip" if the chip is forced.
- Add a new internal programmer parameter boardmismatch=force. This
overrides any mismatch detection from cbtable/image comparisons.
- Add a new internal programmer parameter laptop=force_I_want_a_brick.
- Adjust the documentation for --force.
- Clean up the man page a bit whereever it talks about --force or
laptops.
Additional changes in this patch:
- Add warnings about laptops to the documentation.
- Abort if a laptop is detected. Can be overridden with the programmer
parameter mentioned above.
- Add "Portable" to the list of DMI strings indicating laptops.
- Check if a chip specified with -c is known to flashrom.
- Programmer parameter reliability and consistency fixes.
- More paranoid self-checks.
- Improve documentation.
Corresponding to flashrom svn r996.
