We introduce two new functions to create region objects. They allow us
to check for integer overflows (region_create_untrusted()) or assert
their absence (region_create()).
This fixes potential overflows in region_overlap() checks in SMI
handlers, where we would wrongfully report MMIO as *not* overlapping
SMRAM.
Also, two cases of strtol() in parse_region() (cbfstool), where the
results were implicitly converted to `size_t`, are replaced with the
unsigned strtoul().
FIT payload support is left out, as it doesn't use the region API
(only the struct).

By adding new DCFG (Device Configuration) it allows the

For an example if Bit 0 being set represents Generic DTT UI
access control is disabled and Bit 2 being set represents DTT

Also we don't support DMA on arm platforms in coreboot (only libpayload)
therefore `dma_malloc()` has been removed and `dma_coherent()` has been
moved to architecture specific functions. Any architecture that tries to
use `dma_coherent()` now will get a compile time error. In order to not

so this reimplements it from scratch (that also helps with the
licensing).
This algorithm is prepared to take in a pre-calculated "wide" checksum
in a machine-register-sized data type which is then narrowed down to 16
bits (see RFC 1071 for why that's valid). This isn't used yet (and the
code will get optimized out), but will be used later in this patch
series for architecture-specific optimization.

Commit d252776668 ("tree: Replace And(a,b) with ASL 2.0 syntax")
replaced two instances of `And(var, mask) == 0` with `var & mask == 0`.
This expression needs parentheses - `(var & mask) == 0`.
Without parentheses, it is always false, since the masks are nonzero
(`var & (mask == 0)`; `var & 0`; `0`).
This caused brightness changes on Intel GMA to take longer than
normal since the status was never checked. The brightness would
change immediately, but another brightness change could not occur until
the first change timed out.
This was most noticeable in KDE, which waits for the brightness change
to complete before accepting another brightness up/down keypress.
Tapping brightness up/down repeatedly would take much longer to reach
max/min brightness due to many presses being ignored.
It is noticeable in GNOME as well but less obvious. Tapping brightness
up/down repeatedly would handle all keypresses, but the display's
actual brightness would lag behind and skip some intermediate steps.
I tested both Librem 13v2 and Librem 14, as far as I know this would
apply to all systems configuring brightness with Intel GMA.
Test: Verify brightness keys respond quickly again on Librem 13v2 / 14.

Macros can be confusing on their own; hiding commas make things worse.
This can sometimes be downright misleading. A "good" example would be
the code in soc/intel/xeon_sp/spr/chip.c:
CHIP_NAME("Intel SapphireRapids-SP").enable_dev = chip_enable_dev,
This appears as CHIP_NAME() being some struct when in fact these are
defining 2 separate members of the same struct.
It was decided to remove this macro altogether, as it does not do
anything special and incurs a maintenance burden.

The .inc suffix is confusing to various tools as it's not specific to
Makefiles. This means that editors don't recognize the files, and don't
open them with highlighting and any other specific editor functionality.
This issue is also seen in the release notes generation script where
Makefiles get renamed before running cloc.

This commit adds support for showing different logos on the ChromeOS
firmware splash screen based on the device model (between
Chromebook-Plus and regular ChromeOS devices like Chromebook and
Chromebox). This allows OEMs to customize the branding on their
devices.
This patch also introduces three new Kconfigs:
- CHROMEOS_FW_SPLASH_SCREEN
- CHROMEOS_LOGO_PATH
- CHROMEBOOK_PLUS_LOGO_PATH
which allow users to enable the fw splash screen feature in the
vendorcode. Previously, we were using the BMP_LOGO Kconfig in
drivers/intel/fsp2_0, but we didn't want the top level Kconfigs to be
located inside the architecture specific files.
BUG=b:317880956

The FSP boot mode showing in serial log is a magic number.
In order to let user understand its meaning directly, add
the strings to describe the modes.
TEST=build, boot the device and check the logs:
without this change, the log is like:
[SPEW ] bootmode is set to: 2
with this change:
[SPEW ] bootmode is set to: 2 (boot assuming no config change)
