* Add standalone lightbar simulation toolBill Richardson2014-05-151-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | This adds an "extra/" directory to hold various experiments and optional programs. With this change, we add a tool that can simulate the lightbar behavior on the build machine. That can be used to experment with variations in the lightbar pattern code without needing to reflash a Pixel with a new EC to see the effect. There is no functional change to the EC code, just a couple of #ifdefs to allow common/lightbar.c to be compiled separately from the EC.

| | | | | | | | | | | | | | | | | | | No functional changes, just renaming config options. Remove README, now that all options described in it have been moved to config.h, and the remaining information is out of date. (Yes, we should have a README which describes the organization of the EC repository, but that's a matter for another CL; this one's about cleaning up config options.)

* stm32: Implement keyscan test infrastructureSimon Glass2012-10-311-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Support the keyscan test functionality on stm32. Note: This is enabled by default so that it continues to build. But it is unlikely that we will want this in a shipping image. I suggest we add the facility for a dev build. Secondly, the stack has to be larger due to a printf (which admittedly I could just remove). Should we make the stack size conditional on the CONFIG? Seems a bit ugly, on the other hand we don't want to waste IRAM. BUG=chrome-os-partner:12179 BRANCH=none TEST=manual for now: On snow: ./ectool keyscan 20000 key_sequence.txt See that the test passes.

* stm32: Add an early warning of watchdog firingSimon Glass2012-06-151-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than just reset with no information when we hit a watchdog, try to anticipate the problem and display a trace message as on lm4. This solution is not ideal since we must constantly reset the WWDG to make it work. It may be better to look at dedicating a timer to this purpose instead, since we are really just shadowing the IWDG and don't actually need the reset functionality. One problem is that we now have a fairly short time limit on many operations, since if we can't service an interrupt within about 30ms then the WWDG will reset the system. It also affects JTAG since it seems that the watchdog goes off the first time JTAG is invoked to program the flash. The solution here is to retry. For these reasons it is implemented as an option, CONFIG_WATCHDOG_HELP.
