2017-12-07boardid: Minor clean up and standardizationJulius Werner
Merge the different coreboot table strapping ID structures into one because they're really just all the same, and I want to add more. Make the signature of the board_id() function return a uint32_t because that's also what goes in the coreboot table. Add a printk to the generic code handling strapping IDs in ramstage so that not every individual mainboard implementation needs its own print. (In turn, remove one such print from fsp1_1 code because it's in the way of my next patch.)

2017-12-03ec/lenovo/h8/acpi: Fix regression (MS Windows crash on boot)Patrick Rudolph
Fix a regression introduced by #21227 0709dc04 (ec/lenovo/h8/acpi/thermal: Add ACPI fan control). The commit caused Windows to crash as EC reads aren't allowed in the fan device or it's powerresource's methods. Implement the same approach as all other platforms using a GNVS variable named FLVL instead of reading from EC. In addition to EC reads writing to FIELD elements, in another ACPI scope, seems to be broken. Introduce a new method to set the fan disengage mode. Tested on Windows 7 and Lenovo T500.

2017-11-22chromeec: Change the API for hostevent/wake masks to handle 64-bitFurquan Shaikh
ChromeEC is getting ready to bump up the hostevents and wake masks to 64-bits. The current commands to program hostevents/wake masks will still operate on 32-bits only. A new EC host command will be added to handle 64-bit hostevents/wake masks. In order to prevent individual callers in coreboot from worrying about 32-bit/64-bit, the same API provided by google/chromeec will be updated to accept 64-bit parameters and return 64-bit values. Internally, host command handlers will take care of masking these parameters/return values to appropriate 32-bit/64-bit values.

This patch removes checks that ensure EC to be in RO for recovery boot. We do not need these checks because when recovery is requested automatically (as opposed to manually), we show 'broken' screen where users can only reboot the device or request recovery manually. If recovery is requested, Depthcharge will check whether EC is in RO or not and recovery switch was pressed or not. If it's a legitimate manual recovery, EC should be in RO. Thus, we can trust the recovery button state it reports. This patch removes all calls to google_chromeec_check_ec_image, which is called to avoid duplicate memory training when recovery is requested but EC is in RW.

2017-08-14i2c: Move to Linux like `struct i2c_msg`Nico Huber
Our current struct for I2C segments `i2c_seg` was close to being compa- tible to the Linux version `i2c_msg`, close to being compatible to SMBus and close to being readable (e.g. what was `chip` supposed to mean?) but turned out to be hard to fix. Instead of extending it in a backwards compatible way (and not touching current controller drivers), replace it with a Linux source compatible `struct i2c_msg` and patch all the drivers and users with Coccinelle. The new `struct i2c_msg` should ease porting drivers from Linux and help to write SMBus compatible controller drivers. Beside integer type changes, the field `read` is replaced with a generic field `flags` and `chip` is renamed to `slave`.

This can be used to differentiate wake sources from the EC in the case that the EC has the wake pins from various devices.

2017-05-11mb/lenovo/x201: Add support for ThinkLightStefan Ott
The thinkpad-acpi driver uses the UCMS (CMOS) ACPI method to control the ThinkLight from the Operating System. This patch adds partial support for that method, enough to enable or disable the ThinkLight: echo on >/proc/acpi/ibm/light echo off >/proc/acpi/ibm/light With the original BIOS the UCMS method exposes a wide range of values through a generic /proc/acpi/ibm/cmos interface. With the changes suggested in this patch that interface is also exposed but only accepts the commands to enable or disable the ThinkLight; all other commands are ignored. This change would potentially benefit all currently supported Thinkpad models, I only have an X201 available for tests though.
