2020-03-29nb/intel/haswell: Implement proper backlight PWM configNico Huber
Further backport the backlight-PWM handling from Skylake. Beside configuring the PWM frequency in Hz, we also use the PCH's logic for the brightness setting via BLM_PCH_OVERRIDE_ENABLE. Linux would toggle it anyway and that might confuse our ASL code. We assume that the 183Hz value that was set before for Slippy variants was overridden by Linux with the 200Hz VBT value, like it was for the Broadwell Chromebooks. So we set 200Hz for them in the devicetrees. The calculated value for the T440p of 220Hz seems sane and also matches the VBT.

2020-03-23nb/intel/sandybridge: Void MRC cache if CPUID differsAngel Pons
Native raminit asserts that the DIMMs haven't been replaced before reusing the saved training data. However, it does not check if the CPU is still the same, so it can end up happily reusing data from an Ivy Bridge CPU onto a Sandy Bridge CPU, which runs the raminit_ivy.c code path. This can make the CPU run in unsupported configurations, which may result in an unstable system, or a failure to boot. To prevent that, ensure that the stored CPUID matches the CPUID of the installed CPU. If they differ, print a message and do not use the saved data. As it does not pose a problem for a regular boot, but precludes resuming from S3, use different loglevels depending on the bootpath. Tested on Asus P8Z77-V LX2 with an i7-2600 and an i5-3330, works well.

2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
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.

2020-03-15treewide: Replace uses of "Nehalem"Angel Pons
The code in coreboot is actually for the Arrandale processors, which are a MCM (Multi-Chip Module) with two different dies: - Hillel: 32nm Westmere dual-core CPU - Ironlake: 45nm northbridge with integrated graphics This has nothing to do with the older, single-die Nehalem processors. Therefore, replace the references to Nehalem with the correct names.

2020-03-15nb/intel/nehalem: Rename to ironlakeAngel Pons
The code is for Arrandale CPUs, whose System Agent is Ironlake. This change simply replaces `nehalem` with `ironlake` and `NEHALEM` with `IRONLAKE`. The remaining `Nehalem` cases are handled later, as changing some of them would impact the resulting binary. Tested with BUILD_TIMELESS=1 without adding the configuration options into the binary, and packardbell/ms2290 does not change.
