2022-05-16soc/inte/*/gpio; Add GPE_EN and GPE_STS register definitionMaulik V Vaghela
coreboot needs to set GPE_EN bit for the GPIOs which are wake capable from s0ix/sleep. Due to GPIO locking mechanism, coreboot/OS will not be able to write GPE_EN register post GPIO has been locked. This patch adds support in SoC code to provide correct offset for GPE_EN and GPE_STS registers to the common code. Plan is to use this offsets to set GPE_EN bits before GPIO locking in coreboot which will be part of subsequent CL. BUG=b:222375516 BRANCH=firmware-brya-14505.B TEST=Check if code compiles for Brya and correct offset values are printed.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2018-12-14soc/intel/cannonlake: Add GPIO group pad base for ACPIDuncan Laurie
The GPIO drivers in Windows and Linux for the Cannonlake CPU have a sparse GPIO map and do not allocate pins contiguously. Each GPIO group is allocated as 32 pads regardless of whether the hardware actually has that many in the group. It appears this originated with a bug in Windows/UEFI and was carried over to Linux in order to work with existing firmware: https://lore.kernel.org/patchwork/patch/855244/ In order to support using ACPI GPIOs it is necessary for coreboot to be compatible with this implementation. The GPIO groups that are usable by the OS are declared with a pad base which is then used to compute the number for ACPI GPIOs. BUG=b:120686247 TEST=tested with write protect GPIO on sarien board. Before this change the ACPI pin number was 220 which did not correspond to the pin number in Linux. After this change the ACPI number is 303, which maps to the correct GPIO in Linux. Now the GPIO value reported by the kernel changes when the WP pin is toggled in hardware.
