      Fix broken flash chip base address logic · 816139e0
      Peter Stuge authored 
      
Elan SC520 requries us to deal with flash chip base addresses at locations
other than top of 4GB. The logic for that was incorrectly triggered also when
a board had more than one flash chip. This patch will honor flashbase only when
probing for the first flash chip on the board, and look at top of 4GB for later
chips.

Corresponding to flashrom svn r415 and coreboot v2 svn r3932.

      Only find "unknown .. SPI chip" if no other chip was found · 483b8f0c
      Peter Stuge authored 
      
This removes the false positive matches we've been seeing, and also removes
the true positive match in case there is more than one flash chip and the 2nd
or 3rd are unknown - but I think that case is uncommon enough to warrant the
improvement in the common case. Use flashrom -frc forced read if you have the
uncommon case, and/or please add the flash chip to the flashchips array.

      Force read unknown flash chips · 7ffbc6f9
      Peter Stuge authored 
      
When flash chip detection fails, it is still useful and possible to read the
flash chip contents. If no flash chip is found in normal probes and the
-f -r -c CHIPNAME options are given, a successful probe for the specified
chip is forced, and then flashrom reads the flash chip using either the read
function for the specified chip, or if there is none, a simple memcpy().

The patch also moves the global variable int force in flashrom.c into main()
and passes it as a parameter to layout.c:show_id(), which was the only other
function that used the variable. This is needed to avoid confusion with the
new parameter int force which is added to flashrom.c:probe_flash() and used
to force probe success for the chip named in char *chip_to_probe.
