      One of the problems is that --force had multiple meanings · 27023768

- 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.

      Fix the DOS port · 837d8107
      Rudolf Marek authored 
      
Now the DS selector limit is set to 4GB and all mmio accesses goes
through DS, the 1:1 mapping is fixed so the _DS base is taken onto
account. Plus is that the hwaccess.c needs no change and memcpy etc can
be used on mmaped space.

      Refine and fix the delay loop calculation · 253101e6
      Carl-Daniel Hailfinger authored 
      
The current delay loop calculation is still from revision 1 of flashrom,
and since then it had a logic bug which caused all delays to be twice as
long as intended.

Fix the delay duration.

Protect against delay loop overflows.

Detect a non-working delay loop.

Change the delay loop itself to ensure clever compiler optimizers won't
eliminate it (as happens with clang/llvm in the current code). Some
people suggested machine-specific asm, but the empty asm statement with
the loop counter as register/memory input has the benefit of being
perfectly cross-platform and working in gcc and clang.

If time goes backwards (catastrophical NTP time difference, manual
time change), timing measurements were shot because the new-old time
subtraction yielded negative numbers which weren't handled correctly
because the variable is unsigned. Work around that issue (a fix is
mathematically impossible).

If time goes forward too fast, pick the biggest possible timing
measurement with a guaranteed overflow avoidance for all timing
calculations.

Check four times if the calculated timing is at most 10% too fast. This
addresses OS scheduler interactions, e.g. being scheduled out during
measurement which inflates measurements.

If the timing looks like garbage, recalculate the timer values up to
four times before giving up.

Avoid division by zero in rare cases where timing measurements for a 250
ms delay returned 0 us elapsed.
