2020-03-31drivers/intel/gma: fold gma.asl into default_brightness_levels.aslMatt DeVillier
Including gma.asl at the platform level (vs the board level) means that even desktop boards need to include the default brightness levels, which makes no sense. To begin to clean this up, include gma.asl in default_brightness_levels.asl (as well as the handful of board-specific brightness files) and remove it from the various platforms. A follow-on commit will remove default_brightness_levels.asl from all boards which lack an internal display.

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.

2015-10-23Intel: Move MCRS ResourceTemplate outside of _CRS methodMartin Roth
On Broadwell, this reduces the number of 'remarks' in the IASL build from 222 to 3. Fixes these remarks: Object is not referenced (Name is within method [_CRS]) The ACPI compiler is trying to be helpful in letting us know that we're not using various fields in the MCRS ResourceTemplate when we define it inside of the _CRS method. Since we're not intending to use those objects in the method, it shouldn't be an issue, but the warning is annoying and can mask real issues. Moving the creation of the MCRS object to outside of the CRS method and referencing it from there solves this problem.

2014-11-23sandy/ivy/nehalem: Remerge interrupt handlingVladimir Serbinenko
On those chipsets the pins are just a legacy concept. Real interrupts are messages on corresponding busses or some internal logic of chipset. Hence interrupt routing isn't anymore board-specific (dependent on layout) but depends only on configuration. Rather than attempting to sync real config, ACPI and legacy descriptors, just use the same interrupt routing per chipset covering all possible devices. The only part which remains board-specific are LPC and PCI interrupts. Interrupt balancing may suffer from such merge but: a) Doesn't seem to be the case of this map on current systems b) Almost all OS use MSI nowadays bypassing this stuff completely c) If we want a good balancing we need to take into account that e.g. wlan card may be placed in a different slot and so would require complicated balancing on runtime. It's difficult to maintain with almost no benefit.

The required power MSRs are mirrored in MCHBAR so it is possible to configure TDP at runtime via ASL. This adds the required fields and a set of methods to configure "TDP down" and "TDP nominal". It explicitly does not support "TDP up" at the moment. PSSS: method is added to assist in searching the _PSS table for the appropriate entry that corresponds to the desired max non-turbo ratio. STND: Set TDP Down from Nominal. This will limit CPU to the TDP down configuration by sequencing the required changes in the right order. STDN: Set TDP Nominal from Down. This will set the CPU back to nominal configuration by sequencing the required changes in the correct (reverse) order. This does not introduce any functional changes and must be paired with additional changes to be useful.
