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

This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file()
to cbfs_map() and cbfs_load() respectively. This is supposed to be the
start of a new, better organized CBFS API where the most common
operations have the most simple and straight-forward names. Less
commonly used variants of these operations (e.g. cbfs_ro_load() or
cbfs_region_load()) can be introduced later. It seems unnecessary to
keep carrying around "boot" in the names of most CBFS APIs if the vast
majority of accesses go to the boot CBFS (instead, more unusual
operations should have longer names that describe how they diverge from
the common ones).
cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly
reap mappings when desired. A few new cbfs_unmap() calls are added to
generic code where it makes sense, but it seems unnecessary to introduce
this everywhere in platform or architecture specific code where the boot
medium is known to be memory-mapped anyway. In fact, even for
non-memory-mapped platforms, sometimes leaking a mapping to the CBFS
cache is a much cleaner solution than jumping through hoops to provide
some other storage for some long-lived file object, and it shouldn't be
outright forbidden when it makes sense.
Additionally, remove the type arguments from these function signatures.
The goal is to eventually remove type arguments for lookup from the
whole CBFS API. Filenames already uniquely identify CBFS files. The type
field is just informational, and there should be APIs to allow callers
to check it when desired, but it's not clear what we gain from forcing
this as a parameter into every single CBFS access when the vast majority
of the time it provides no additional value and is just clutter.

Create two new functions to fetch mrc_cache data (replacing
mrc_cache_get_current):
- mrc_cache_load_current: fetches the mrc_cache data and drops it into
the given buffer. This is useful for ARM platforms where the mmap
operation is very expensive.
- mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a
given buffer. This is useful for platforms where the mmap operation
is a no-op (like x86 platforms). As the name mentions, we are not
freeing the memory that we allocated with the mmap, so it is the
caller's responsibility to do so.
Additionally, we are replacing mrc_cache_latest with
mrc_cache_get_latest_slot_info, which does not check the validity of
the data when retrieving the current mrc_cache slot. This allows the
caller some flexibility in deciding where they want the mrc_cache data
stored (either in an mmaped region or at a given address).

After correcting them, SeaBIOS can boot from SATA on Asrock Q1900M.

zero in the FADT.
Since the FADT struct defaults to zero in coreboot, we don't need to do
anything with PM1b for now. So, drop unneeded writes to PM1b fields.
Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of
the patch train, both operating systems are able to boot successfully.

None of the currently-supported chips has a GPE1 block. The ACPI spec,
version 6.3, section 4.8.1.6 (General-Purpose Event Registers) says:
If a generic register block is not supported then its respective
block pointer and block length values in the FADT table contain zeros.

Intel southbridges do this. Also make `acpi_sci_irq` non-static as it is
needed outside acpi.c with this change.
