* Fix broken flash chip base address logicPeter Stuge2009-02-091-1/+1
| | | | | | | | | | | | | 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.

* Force read unknown flash chipsPeter Stuge2008-06-181-6/+45
| | | | | | | | | | | | | | | | | | | 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.

* Probe for up to 3 flash chipsClaus Gindhart2008-05-081-3/+19
| | | | | | | | | | | | | | | | | | | Currently there is an ongoing technology migration from LPC/FWH to SPI chips. For this reason some boards have multiple chips of different technologies onboard. This patch makes flashrom probe for up to 3 chips and if more than one chip is found flashrom exits, asking the user to specify -c. [root@localhost src]# ./flashrom ...
