Currently the VBIOS is placed somewhere in DRAM when necessary.
While generating ACPI tables the code attempts to find the VBIOS
by looking at "known" places.
Simplify the code and keep track of the VBIOS using a pointer in
struct device by filling it in pci_rom_load().
The following patches will reuse this pointer to generalize the
code even more.

As per commit 8651731537 ("sconfig: Move config_of_soc from device.h
to static.h") and commit 05a13e7ed9 ("sconfig: Move (WEAK_)DEV_PTR
from device.h to static.h"), sources that require access to the
devicetree should directly include static.h. This allows static.h to be
removed from device.h, eliminating many unnecessary dependencies on the
devicetree for objects that only need the device types and function
declarations.
Now that static.h has been included throughout the tree where necessary,
it can be removed from device.h.

Similar to commit 8651731537 ("sconfig: Move config_of_soc from
device.h to static.h"), move these macros to static.h to separate
dependencies on device.h and static.h. These macros resolve to device
alises that are declared in the generated static_devices.h header, so
move them to static.h which includes static_devices.h.
Since static.h remains included in device.h, any source that uses these
macros should still compile correctly. Subsequent commits will add
static.h to files that need them, after which static.h can be dropped
from device.h.

Many sources include device.h and thus static.h, but many only need the
function declarations and type definitions, not the compiled devicetree
from sconfig. This causes many unnecessary recompiles whenever the
devicetree is updated due to the dependency. Address this by moving the
config_of_soc macro directly into the generated static.h header, as it
seems to be the only line in device.h that actually requires static.h.
For now, static.h remains included in device.h so that the build is not
affected. Subsequent commits will include static.h directly into sources
that actually need it, after which it can be dropped from device.h.
Some statistics for C objects:
Dell Latitude E6400 (GM45/ICH9):
669 total objects
181 depend on static.h
2 require static.h
Dell Latitude E6430 (Ivy Bridge/Panther Point):
693 total objects
199 depend on static.h
3 require static.h
Lenovo ThinkCentre M700 / M900 Tiny (Kaby Lake):
794 total objects
298 depend on static.h
23 objects require static.h
MSI PRO Z690-A (WIFI) DDR4 (Alder Lake):
959 total objects
319 depend on static.h
25 require static.h
The number of objects was determined by grepping the build log for
calls to CC, the number of objects that depend on static.h was
determined by grepping for calls to CC after touching static.h, and the
number of objects that actually require the static.h related lines from
device.h was determined by grepping for objects that failed to build
after removing the static.h lines from device.h and running make with
the --keep-going flag.

To avoid having constructs like 'dev->path.domain.domain' in the SoC
code, create the 'dev_get_domain_id' helper function that returns the
domain ID of either that device if it's a domain device or the
corresponding domain device's domain ID, and use it in the code.
If this function is called with a device other than PCI or domain type,
it won't have a domain number. In order to not need to call 'die',
'dev_get_domain_id' will print an error and return 0 which is a valid
domain number. In that case, the calling code should be fixed.

CXL (Compute Express Link) [1] is a cache-coherent interconnect
standard for processors, memory expansion and accelerators.
CXL memory is provided through CXL device which is connected
through CXL/PCIe link, while regular system memory is provided
through DIMMs plugged into DIMM slots which are connected to
memory controllers of processor.
With CXL memory, the server's memory capacity is increased.
CXL memory is in its own NUMA domain, with longer latency
and added bandwidth, comparing to regular system memory.
Host firmware may present CXL memory as specific purpose memory.
Linux kernel dax driver provides direct access to such differentiated
memory. In particular, hmem dax driver provides direct access to
specific purpose memory.
Specific purpose memory needs to be represented in e820 table as
soft reserved, as described in [2].
Add IORESOURCE_SOFT_RESERVE resource property to indicate (memory)
resource that needs to be soft reserved.
Add soft_reserved_ram_resource macro to allow soc/mb code to add

This patch extends the available device paths with a new device 'mdio'.
MDIO is the 'Management Data Input/Output' called interface which is
used to access an Ethernet PHY behind a MAC to change settings. The real
payload data path is not handled by this interface.
To address the PHY correctly on the MDIO bus, there is a 5 bit address
needed, which often can be configured via pins on the mainboard.
Therefore, the new introduced device has an 'addr' field to define its
address. If one wants to use a MDIO device in devicetree, the syntax is
straight forward (example):
device mdio 0x2 on end
As the MDIO interface is driven by the MAC, most likely this MDIO device
will be hooked in as a child device of the (PCI attached) MAC device.
With the new introduced ops_mdio a new interface is added to provide an
API for read and write access over MDIO.

The `IORESOURCE_ABOVE_4G` flag was only explicitly set for our dummy
device that reserves resources behind a hotplug port. The current re-
source allocator implicitly extends this to all devices below the port,
including real ones. Let's make that explicit, so future changes to the
allocator can't break this rule.

This adds SPDX-License-Identifiers to all of the files in src/include
that are missing them or have unrecognized identifiers.
Files that were written specifically for coreboot and don't have license
information are licensed GPL-2.0-only, which is the license for the
overall coreboot project.
Files that were sourced from Linux are similarly GPL-2.0-only.
The cpu/power files were committed with source that was licensed as
GPL-2.0-or-later, so presumably that's the license for that entire
commit.
The final file, vbe.h gives a pointer to the BSD-2-Clause license
at opensource.org.

Function fixed_io_resource() and alias io_resource() were
previously unused. Unlike previously, IORESOURCE_STORED flag
needs to be set by the caller, when necessary.
For fixed resources, fields alignment, granularity and
limit need not be initialised, as the resource cannot
be moved. It is assumed the caller provides valid base
and size parameters.

Unlike fixed_mem_resource_kb() the arguments are not in KiB.
This allows coccinelle script to assign the base and size
without applying the KiB division or 10 bit right-shift.
Unlike with fixed_mem_resource_kb() the IORESOURCE_STORED flag is
passed in the flags parameter until some inconsistencies in the tree
get resolved.
