* One of the problems is that --force had multiple meaningsCarl-Daniel Hailfinger2010-04-281-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

* Internal (onboard) programming was the only feature which could not be disabledCarl-Daniel Hailfinger2009-12-131-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Make various pieces of code conditional on support for internal programming. Code shared between PCI device programmers and onboard programming is now conditional as well. It is now possible to build only with dummy support: make CONFIG_INTERNAL=no CONFIG_NIC3COM=no CONFIG_SATASII=no CONFIG_DRKAISER=no CONFIG_SERPROG=no CONFIG_FT2232SPI=no This allows building for a specific use case only, and it also facilitates porting to a new architecture because it is possible to focus on highlevel code only. Note: Either internal or dummy programmer needs to be compiled in due to the current behaviour of always picking a default programmer if -p is not specified. Picking an arbitrary external programmer as default wouldn't make sense. Build and runtime tested in all 1024 possible build combinations. The only failures are by design as mentioned above.

* Adept layout handling to new programmer infrastructure and fix off-by-one errorCarl-Daniel Hailfinger2009-08-191-6/+5
| | | | | | | | | | | | | Flashrom has the ability to use layout files with romentries, but this feature was not adapted to the programmer infrastructure and had undefined behaviour for flasher!=internal. The romentry handling had an off-by-one error which caused all copies to end up one byte short. Fix these issues. Corresponding to flashrom svn r694.

* Sometimes we want to read/write more than 4 bytes of chip content at onceCarl-Daniel Hailfinger2009-06-051-0/+1
| | | | | | | | | | | | | | | | | | | | Add chip_{read,write}n to the external flasher infrastructure which read/write n bytes at once. Fix a few places where the code used memcpy/memcmp although that is strictly impossible with external flashers. Place a FIXME in the layout.c code because usage is not totally clear and needs to be fixed to support external flashers. As a nice side benefit, we get a noticeable speedup for builtin flash reading which is now a memcpy() of the full flash area instead of a series of single-byte reads.

* Force read unknown flash chipsPeter Stuge2008-06-181-3/+1
| | | | | | | | | | | | | | | | | | | 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.
