2019-04-11chromeos: clean up "recovery" and "write protect" GPIOsJoel Kitching
The "write protect" GPIO's cached value is never actually read after entering depthcharge. Ensure the value from get_write_protect_state() is being transferred accurately, so that we may read this GPIO value in depthcharge without resampling. The cached value of the "recovery" GPIO is read only on certain boards which have a physical recovery switch. Correct some of the values sent to boards which presumably never read the previously incorrect value. Most of these inaccuracies are from non-inverted values on ACTIVE_LOW GPIOs.

2017-03-28vboot: Assume EC_SOFTWARE_SYNC and VIRTUAL_DEV_SWITCH by defaultJulius Werner
The virtualized developer switch was invented five years ago and has been used on every vboot system ever since. We shouldn't need to specify it again and again for every new board. This patch flips the Kconfig logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the latter for Lumpy which seems to have been omitted incorrectly, and hide it from menuconfig since it's a hardware parameter that shouldn't be configurable.) Since almost all our developer switches are virtual, it doesn't make sense for every board to pass a non-existent or non-functional developer mode switch in the coreboot tables, so let's get rid of that. It's also dangerously confusing for many boards to define a get_developer_mode() function that reads an actual pin (often from a debug header) which will not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set. Therefore, this patch removes all those non-functional instances of that function. In the future, either the board has a physical dev switch and must define it, or it doesn't and must not. In a similar sense (and since I'm touching so many board configs anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC. Instead, it should just be assumed by default whenever a Chrome EC is present in the system. This way, it can also still be overridden by menuconfig.

2016-11-18google/chromeec: Add common infrastructure for boot-mode switchesFurquan Shaikh
Instead of defining the same functions for reading/clearing boot-mode switches from EC in every mainboard, add a common infrastructure to enable common functions for handling boot-mode switches if GOOGLE_CHROMEEC is being used. Only boards that were not moved to this new infrastructure are those that do not use GOOGLE_CHROMEEC or which rely on some mainboard specific mechanism for reading boot-mode switches. BUG=None BRANCH=None TEST=abuild compiles all boards successfully with and without ChromeOS option.

2016-07-30chromeos mainboards: remove chromeos.aslAaron Durbin
Use the ACPI generator for creating the Chrome OS gpio package. Each mainboard has its own list of Chrome OS gpios that are fed into a helper to generate the ACPI external OIPG package. Additionally, the common chromeos.asl is now conditionally included based on CONFIG_CHROMEOS.

2016-04-05chromeos: Simplify fill_lb_gpios even furtherJulius Werner
A long time ago many Chrome OS boards had pages full of duplicated boilerplate code for the fill_lb_gpios() function, and we spent a lot of time bikeshedding a proper solution that passes a table of lb_gpio structs which can be concisely written with a static struct initializer in http://crosreview.com/234648. Unfortunately we never really finished that patch and in the mean time a different solution using the fill_lb_gpio() helper got standardized onto most boards. Still, that solution is not quite as clean and concise as the one we had already designed, and it also wasn't applied consistently to all recent boards (causing more boards with bad code to get added afterwards). This patch switches all boards newer than Link to the better solution and also adds some nicer debug output for the GPIOs while I'm there. If more boards need to be converted from fill_lb_gpio() to this model later (e.g. from a branch), it's quite easy to do with: s/fill_lb_gpio(gpio++,\n\?\s*\([^,]*\),\n\?\s*\([^,]*\),\n\?\s*\([^,]*\),\n\?\s*\([^,]*\));/\t{\1, \2, \4, \3},/ Based on a patch by Furquan Shaikh <furquan@google.com>.
