Target added to INTERMEDIATE all operate on coreboot.pre, each modifying
the file in some way. When running them in parallel, coreboot.pre can be
read from and written to in parallel which can corrupt the result.
Add a function to create those rules that also adds existing
INTERMEDIATE targets to enforce an order (as established by evaluation
order of Makefile.inc files).
While at it, also add the addition to the PHONY target so we don't
forget it.

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.

IASL version 20180927 and greater, detects Unnecessary/redundant uses of
the Offset() operator within a Field Unit list.
It then sends a remark "^ Unnecessary/redundant use of Offset"
example:
OperationRegion (OPR1, SystemMemory, 0x100, 0x100)
Field (OPR1)
{
Offset (0), // Never needed
FLD1, 32,
Offset (4), // Redundant, offset is already 4 (bytes)
FLD2, 8,
Offset (64), // OK use of Offset.
FLD3, 16,
}
We will have those remarks:
dsdt.asl 14: Offset (0),
Remark 2158 - ^ Unnecessary/redundant use of Offset operator
dsdt.asl 16: Offset (4),
Remark 2158 - ^ Unnecessary/redundant use of Offset operator

I would like to make assertions evaluate at compile time where possible,
but sometimes people used a literal assert(0) to force an assertion in a
certain code path. We already have BUG() for that so let's just replace
those instances with that.

All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as
reset register in FADT. How unsurprising. We might as well use that
information to automatically fill in the FADT accordingly. So, do it.
To avoid having x86-specific code under arch-agnostic `acpi/`, create a
new optional `arch_fill_fadt` function, and override it for x86 systems.

Instead, just flip the desired bits using bitwise operations. As this is
initially zero, the resulting value is the same. This allows flags to be

The PM2_CNT register block is no longer needed, as explained in some
comments. While they may have been copy-pasted around a lot, they are at
least true for Hudson, and it makes sense to assume that they are true
for newer chipsets as well. As per the ACPI specification, version 6.3,
section 4.8.1.3 (PM2 Control Register):
This register block is optional, if not supported its block pointer and
length contain a value of zero.
Since the FADT struct defaults to zero in coreboot, we don't need to do
anything to indicate PM2_CNT is not supported. So, drop unneeded values.

sections 4.8.1.1 and 4.8.1.2 (PM1 Event/Control Registers):

Since the FADT struct defaults to zero in coreboot, we don't need to do
