2022-04-20ec/google/chromeec: Drop `_PRS` from static devicesAngel Pons
The `_PRS` ACPI object is not needed for static (non-configurable) devices. For devices where `_CRS` always provides the same set of resource settings, drop the `_PRS` object. Note that every dropped `_PRS` object only provides one set of resource settings, which is identical to the resource settings provided by the `_CRS` object.

2022-03-17ec/chromeec/ec_smbios: Set system manufacturer for ChromeOS devicesMatt DeVillier
Currently, many Linux drivers use DMI quirks to identify ChromeOS devices and handle them accordingly: namely they look for the SMBIOS system manufactuer to be "GOOGLE" or "Google", and the bios-vendor to be coreboot. Historically this was consistently the case, but recent model ChromeOS devices allow the OEM to set the mainboard manufacturer, which is also the default system manufacturer. This breaks many DMI quirks, notably ones used by SOF (sound open firmware) for audio. To fix this, set the system manufactuer for ChromeOS devices to "Google" for devices selecting CONFIG_EC_GOOGLE_CHROMEEC_SKUID, leaving the OEM customization in place for the mainboard manufacturer. Since boards selecting CONFIG_EC_GOOGLE_CHROMEEC_SKUID are the only ones overriding the default mainboard manufacturer, they are the only ones which need this correction. Test: build/boot google/bloog with Linux 5.16, verify SOF drivers correctly detect device as a Chromebook and load the appropriate audio firmware.

2022-02-07treewide: Remove "ERROR: "/"WARN: " prefixes from log messagesJulius Werner
Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size. This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result.

2021-06-17ec/google: Fix bad return valueRob Barnes
google_chromeec_get_event returns an event number and 0 when there's no event.

2020-07-22ec/google/chromeec: Fix Coverity Scan error (BAD_SHIFT)Tim Wawrzynczak
A recent Coverity scan found an issue with the way the EC_HOST_EVENT_MASK macro was being used. It was being passed values between 0 and 63, but since it is doing basically (1ULL << (value - 1)), this caused a shift of -1 when `i` is 0 and also doesn't reach the 63rd bit of the mask. This is fixed by incrementing the start and end conditions of the loop by 1, so the event mask ranges from bits 0 to 63, instead of -1 to 62.

2020-04-22ec/google/chromeec: Fix acpi_name() for Chrome EC deviceFurquan Shaikh
In ACPI tables, Chrome EC device (CREC - HID GOOG0004) is a child of EC device (EC0 - HID PNP0C09). However, in coreboot device tree, there is no separate chip/device for EC0. Thus, acpi_name() needs to return EC0.CREC as the ACPI name for the Chrome EC device. By returning the ACPI name as EC0.CREC, all devices that live under Chrome EC device can simply call acpi_device_path()/acpi_device_scope() to emit the right path/scope. In the future, if we ever add a special chip driver for handling EC0 (HID PNP0C09), then the ACPI name for Chrome EC can be fixed to return CREC.
