* Change semantics of image building in the layout code.hailfinger2010-11-021-21/+51
| | | | | | | | | | | | | | | | | If a layout file was specified, all regions not mentioned in the layout file were taken from the new image instead of being preserved. If regions overlap, the non-included regions won. New behaviour: If a layout file is specified, only the regions explicitly requested for inclusion will be taken from the new image. If regions overlap, the included regions win.

* Always read the flash chip before writing. This will allow flashrom tohailfinger2010-10-191-5/+4
| | | | | | | | | | | | | | | | | | | | | | skip erase of already-erased blocks and to skip write of blocks which already have the wanted contents. Avoid emergency messages by checking if the chip contents after a failed write operation (erase/write) are unchanged. Keep the emergency messages after a failed pure erase. That part is debatable because if someone wants erase, he pretty sure doesn't care about the flash contents anymore. Please note that this introduces additional overhead of a full chip read before write. This is frowned upon by people with slow programmers. A followup patch will make this configurable.

* Kill global variables, constants and functions if local scope suffices.hailfinger2010-07-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Constify variables where possible. Initialize programmer-related variables explicitly in programmer_init to allow running programmer_init from a clean state after programmer_shutdown. Prohibit registering programmer shutdown functions before init or after shutdown. Kill some dead code. Rename global variables with namespace-polluting names. Use a previously unused locking helper function in sst49lfxxxc.c. This is needed for libflashrom. Effects on the binary size of flashrom are minimal (300 bytes shrinkage), but the data section shrinks by 4384 bytes, and that's a good thing if flashrom is operating in constrained envionments.

* --force may have been a good idea back when only developers were usinghailfinger2010-04-281-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flashrom, but over the last few months we've seen too many people who incorrectly believed that --force would solve anything. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | disabled. 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.

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.

| | | | | | | | | | | | | | | | | | | | | | flashrom: Force read unknown flash chips 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.
