Previously, SMBUS support was not required for Apollo Lake, since the
SPD was read inside FSP-M, during memory initialization. However, the

to the processor via SMBUS. This patch adds SMBUS common driver support
for Apollo Lake to initialize this HWM.

The bus master bit is set at many places in coreboot's code, but the
reason for that is not quite clear. We examined not setting the
bus master bit whereever possible and tried booting without it,
which worked fine for internal PCI devices but not for PCIe. As a PCIe
device we used a Samsung M.2 NVMe SSD.
For security reasons, we would like to disable bus mastering where
possible. Depending on the device, bus mastering might get enabled
by the operating system (e.g. for iGPU) and it might be required for
some devices to work properly. However, the idea is to leave it disabled
and configure the IOMMU first before enabling it.
To have some sort of "backwards compatibility", add a method which
configures bus mastering based on an additional config option. Since
CB:42460 makes usage of this treewide, enable it by default to keep the
current behaviour for now.

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.

This change introduces a new top-level interface for interacting with a
bitmask providing firmware configuration information.
This is motivated by Chromebook mainboards that need to support multiple
different configurations at runtime with the same BIOS. In these
devices the Embedded Controller provides a bitmask that can be broken
down into different fields and each field can then be broken down into
different options.
The firmware configuration value could also be stored in CBFS and this
interface will look in CBFS first to allow the Embedded Controller value
to be overridden.
The firmware configuration interface is intended to easily integrate
into devicetree.cb and lead to less code duplication for new mainboards
that make use of this feature.
BUG=b:147462631
TEST=this provides a new interface that is tested in subsequent commits

This change adds back CB:39487 which was reverted as part of
CB:41412. Now that the resource allocator is split into old(v3) and
new(v4), this change adds support for allocating resources above 4G
boundary with the new allocator v4.
Original commit message:
This change adds support for allocating resources above the 4G
boundary by making use of memranges for resource windows enabled in
the previous CL.
It adds a new resource flag IORESOURCE_ABOVE_4G which is used in the
following ways:
a) Downstream device resources can set this flag to indicate that they
would like to have their resource allocation above the 4G
boundary. These semantics will have to be enabled in the drivers
managing the devices. It can also be extended to be enabled via
devicetree. This flag is automatically propagated by the resource
allocator from downstream devices to the upstream bridges in pass
1. It is done to ensure that the resource allocator has a global view
of downstream requirements during pass 2 at domain level.
b) Bridges have a single resource window for each of mem and prefmem
resource types. Thus, if any downstream resource of the bridge
requests allocation above 4G boundary, all the other downstream
resources of the same type under the bridge will be allocated above 4G
boundary.
c) During pass 2, resource allocator at domain level splits
IORESOURCE_MEM into two different memory ranges -- one for the window
below 4G and other above 4G. Resource allocation happens separately
for each of these windows.
d) At the bridge level, there is no extra logic required since the
resource will live entirely above or below the 4G boundary. Hence, all
downstream devices of any bridge will fall within the window allocated
to the bridge resource. To handle this case separately from that of
domain, initializing of memranges for a bridge is done differently
than the domain.
Limitation:
Resources of a given type at the bridge or downstream devices
cannot live both above and below 4G boundary. Thus, if a bridge has
some downstream resources requesting allocation for a given type above
4G boundary and other resources of the same type requesting allocation
below 4G boundary, then all these resources of the same type get
allocated above 4G boundary.
