The layout of GNVS has expectation for a fixed size
array for chromeos_acpi_t. This allows us to reduce
the exposure of <chromeos/gnvs.h>.
If chromeos_acpi_t was the last entry in struct global_nvs
padding at the end is also removed.
If device_nvs_t exists, place a properly sized reserve for
chromeos_acpi_t in the middle.
Allocation from cbmem is adjusted such that it matches exactly
the OperationRegion size defined inside the ASL.

Trying to do multiple operations on the same CBFS image at the same time
likely leads to data corruption. For this reason, add BSD advisory file
locking (flock()) to cbfstool (and ifittool which is using the same file
I/O library), so that only one process will operate on the same file at
the same time and the others will wait in line. This should help resolve
parallel build issues with the INTERMEDIATE target on certain platforms.
Unfortunately, some platforms use the INTERMEDIATE target to do a direct
dd into the CBFS image. This should generally be discouraged and future
platforms should aim to clearly deliminate regions that need to be
written directly by platform scripts with custom FMAP sections, so that
they can be written with `cbfstool write`. For the time being, update
the legacy platforms that do this with explicit calls to the `flock`
utility.

Setting registers 64h[19:18] = 2 and 68h[14:13] = 3 enables OBFF, and
setting registers 64h[19:18] = 0 and 68h[14:13] = 0 disables OBFF.
Register at offset 0x64 is DCAP2, and offset 0x68 is DCTL2.
However, current code doesn't account for this. The result is that
register 64h[19:18] = 2 and 68h[14:13] = 0, which means the hardware is
OBFF-capable but support is disabled, which makes no sense. Given that
reference code and Broadwell both disable OBFF, disable it here too.

Several changes[1][2] to the Linux kernel now enable ASPM/AER for the
rt8169 network driver, for which it was previously disabled. This,
coupled with the southbridge enabling AER for all PCIe devices, has
resulted in a large amount of AER timeout errors in the kernel log for
boards which utilize the rt8169 for on-board Ethernet (e.g., google/beltino).
While performance is not impacted, the errors do accumulate.
To mitigate this, guard AER enablement via Kconfig, select it by default
(as to maintain current default behavior), and allow boards which need
to disable it to do so (implemented in subsequent commits).
This implementation is derived from that in soc/intel/broadwell.
Test: build/boot google/beltino variants with AER disabled (CB:46136),
verify dmesg log free of AER timeout errors.

there are two different `mei_base_address` global variables, and we have

The duplicate global in `me.c` and `me_8.x.c` will be completely gone
once this new `me_common.c` file becomes a standalone compilation unit.
We are wrapping some things in static inline functions, as they won't be

cases, this affects the last function. The PCIe init code will never
finish configuring the root ports if that is the case: it assumes that
the last function will eventually run through the code, but it doesn't.
If PCIe initialization does not complete, pressing the power button will
not power off the board, unless it is held for about five seconds. Also,
Windows 10 will show a BSOD about MACHINE CHECK EXCEPTION, and lock up
instead of rebooting. Depending on the microcode version, the BSOD may
not be visible. This happens even when the root port is not populated.
Use the strap fuse configuration value to know which configuration the
PCH is strapped to. If needed, update the number of ports accordingly.
In addition, print the updated value to ease debugging PCIe init code.
Existing code in coreboot disagrees with public documentation about the
root port width straps. Assume existing code is correct and document
these assumptions in a table, as an explanation for the added code.
Tested on Asrock B85M Pro4, PCIe initialization completes successfully.

Looks like no one really knows what this bit would be useful for, nor
when it would need to be set. Especially if coreboot is setting it even
on PCI *Express* bridges. Digging through git history, nearly all
instances of setting it on PCIe bridges comes from i82801gx, for which
no reason was given as to why this would be needed. The other instances
in Intel code seem to have been, unsurprisingly, copy-pasted.
Drop all uses of this definition and rename it to avoid confusion. The
negation in the name could trick people into setting this bit again.
Tested on Asrock B85M Pro4, no visible difference.
