      Add support for AMIC Technology A49LF040A and do not probe W29EE011 anymore · b9f61744
      Jens Kuehnel authored 
      
Jens sent the first patch that added A49LF040A to flash.h and flashchips.c
using _jedec and _49lf040 functions.

An issue was found with probe_w29ee011() for the Winbond W29EE011, which
caused the A49LF040A to no longer respond to any commands.

Ward made a patch to disable probing by default for the W29EE011 following
some discussion. Using -c W29EE011 will make flashrom probe for the chip.

Peter did some more datasheet diving and found that the Pm49FL00x functions
suited this chip quite well because of the block locking registers in
A49LF040A, and finally tested PROBE READ ERASE WRITE to work on ALIX.3c3.

Ward confirmed that this works on alix.2c3 too.

Corresponding to flashrom svn r260 and coreboot v2 svn r3368.

      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.

Corresponding to flashrom svn r259 and coreboot v2 svn r3367.

      Mark SST SST49LF160C as fully supported.: · 1dbb9af1
      Peter Stuge authored 
      
SST SST49LF160C is confirmed to work for PROBE READ ERASE WRITE, at least on
2 MCP55-based boards (gigabyte m57sli v1 and supermicro h8dmr).

On the m57sli board, it only works > 512K when booted into coreboot; the
proprietary bios seems to do something weird where it locks rom access down
to the first 512K of the chip.

Corresponding to flashrom svn r255 and coreboot v2 svn r3360.
