a6a64183d6 nb/intel/sandybridge: Void MRC cache if CPUID differs
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.

factoring out the register groups using loops.

f3f36faf35 src (minus soc and mainboard): Remove copyright notices
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.

31b7ee4201 treewide: Replace uses of "Nehalem"
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.

1db5bc7dac nb/intel/haswell: Tidy up code and comments
- Reformat some lines of code
- Put names to all used MCHBAR registers
- Move MCHBAR registers into a separate file, for future expansion
- Rewrite several comments
- Use C-style comments for consistency
- Rewrite some hex constants
- Use HOST_BRIDGE instead of PCI_DEV(0, 0, 0)

Tested, it does not change the binary of Asrock B85M Pro4.

Erratum is for Mobile Intel ® 945 Express Chipset family.

So rename 'fixup_i945_errata()' to 'fixup_i945gm_errata()' and apply
that function only for I945GM.

5e5e789f9b nb/intel/haswell/peg: Add PEG driver stub
This is a port of https://review.coreboot.org/c/coreboot/+/22337 to the
Haswell northbridge.  This code is necessary to support the dGPU of the
t440p. Code was cut and pasted from Sandy Bridge with vendor IDs updated
to the correct Haswell values.  Tested on t440p with dGPU on Ubuntu
18.04.4 with 5.3.0-28 kernel. Without patches dmesg reports Nouveau is
unable to read the VBIOS of the dGPU as it has an invalid checksum (I
checked that the ROM in CBFS is correct). With this patch DRM works
correctly with both the Nouveau driver and the Nvidia proprietary
driver. Windows 10 1909 also tested but generates bluescreen once GPU
driver is loaded.

2b6d249632 nb/intel/snb: Add PCI routing table for PEG root ports
Previously the PRTs were defined in southbridge code (8014714
southbridge/intel/bd82x6x/acpi: Fix IRQ warnings), but this was lost
when southbridge PRTs became autogenerated. Add the proper PRTs for the
PCI express for graphics root ports.

This (again) fixes warnings issued by Linux for interrupts on secondary
functions of devices on the PEG ports, such as the HDMI audio controller
on graphics cards.

    pcieport 0000:00:01.0: can't derive routing for PCI INT B
    snd_hda_intel 0000:01:00.1: PCI INT B: no GSI
