We currently have two competing mechanisms to limit the placement of
resources:
1. the explicit `.limit` field of a resource, and
2. the IORESOURCE_ABOVE_4G flag.
This makes the resource allocator unnecessarily complex. Ideally, we
would always reduce the `.limit` field if we want to "pin" a specific
resource below 4G. However, as that's not done across the tree yet,
we will use the _absence_ of the IORESOURCE_ABOVE_4G flag as a hint
to implicitly lower the `limit` of a resource. In this patch, this
is done inside the effective_limit() function that hides the flag
from the rest of the allocator.
To automatically place resources above 4G if their limit allows it,
we have to allocate from top down. Hence, we disable the prompt for
RESOURCE_ALLOCATION_TOP_DOWN and turn it on by default. Platforms
that are incompatible should be fixed, but can also override the
default as a temporary measure.
One implication of the changes is that we act differently when a
cold-plugged device reports a prefetchable resource with 32-bit
limit. Before this change, we would fail to allocate the resource.
After this change, it forces everything on the same root port below
the 4G line.
A possible solution to get completely rid of the IORESOURCE_ABOVE_4G
flag would be rules to place resources of certain devices below 4G.
For instance, the primary VGA device and storage and HID devices
could be made available to a payload that can only address 32 bits.
For now, effective_limit() provides us enough abstraction as if the
`limit` would be the only variable to consider. With this, we get
rid of all the special handling of above 4G resources during phase 2
of the allocator. Which saves us about 20% of the code :D
An earlier version of this change (commit 117e436115) had to be
reverted because of missing resource reservations in platform code.
This is worked around now with commit ae81497cb6 (device/pci:
Limit default domain memory window).

When the default pci_domain_read_resources() is used,
keep 32-bit memory resources below the limit given by
CONFIG_DOMAIN_RESOURCE_32BIT_LIMIT. This serves as a
workaround for missing/wrong reservations of chipset
resources.
This will help to get more stable results from our own
allocator, but is far from a complete solution. Indvi-
dual platform ASL code also needs to be considered, so
the OS won't assign conflicting resources.
Most platforms have reserved space between 0xfe000000
and the 4G barrier. So use that as a global default.
In case of `soc/intel/common/`, use 0xe0000000 because
this is what is advertised in ACPI and there are traces
of resources below 0xfe000000 that are unknown to core-
boot's C code (PCH_PRESERVED_BASE?).
Tested on QEMU/Q35 and Siemens/Chili w/ and w/o top-

Don't assume only one IO and one MEM domain resource.
Currently the code is awkward for bridge devices where loops over
resources are done twice. This would be avoided on top of other patches
that improve the allocator (topic:allocator) by adding a top-down mode.
However those patches break the tree and having the option to have
multiple resources per type would make it easier to get those patches in
without breaking the tree.

The rationale behind this change is that multiple nested bridges using a
lot of bus numbers and IO resources is not likely to be a common hotplug
setup. When there is a large amount of hotplug ports using 32
subordinate busses results in boot failures (e.g. make qemu). 8K IO
busses for hotplug devices is also excessive in most use cases when only
64K is available in total (again make qemu results in failure to
allocate resources but does boot to payload).

The Common Clock Configuration (CCC) is a PCIe feature for cases where
the upstream and downstream device of a link share the same reference
clock. After a change in this setting a link re-training is mandatory
to make it effective.
On recent Intel platforms (tested on Elkhart Lake) the FSP code which is
executed before coreboot performs the PCI scan already enumerates all
PCI buses for its internal uses. While this is done, all the PCI express
features of a link are configured, which includes CCC. If the link
supports common clock, FSP performs the link re-training already. When the
execution flow is returned to coreboot, the same link treatment is
applied again (coded in 'pciexp_tune_dev()') and CCC is enabled a second
time, just a few milliseconds after FSP did this already.
Because enabling CCC requires a link re-training, there are two link
re-trainings on the PCIe link within a few milliseconds (one from the FSP
code and one from coreboot) which can lead to issues with a connected
PCIe device on this link. In particular, link issues were discovered
with a Pericom PCIe switch (PI7C9X2G608) on mc_ehl1 where the link has
stalled for a while after the second re-training. This in turn leads to
non-initialized PCI devices on the bus after coreboot has finished.
This patch checks if CCC is already enabled on a link and does not
perform the steps to enable it again in coreboot which safes a link
re-training (and thus execution time) and a potential link stability
issue.
Test=Check log output on mc_ehl1 which shows the following lines:
[DEBUG] PCI: pci_scan_bus for bus 09
[DEBUG] PCI: 09:00.0 [8086/1533] enabled

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.

Currently, we're building support for all memory types into every board,
and letting the linker remove anything that isn't needed. This is okay,
but it'd be nice to be able to build in just what's actually needed.
This change adds options to specify both what is used and what is not.
By doing it that way, the default values don't change, but platforms can
start removing support for memory types that are not needed. When all
platforms (SoCs, CPUs and/or Northbridge chips) specify what memory
types they support, the defaults on the options to use a particular
memory type can be set to no, and the options not to use a memory type
can be removed.

Refer to PCI Express Base rev6.0 v1.0, 4.2.7 Link Training and Status
State Rules, Lane Error Status is normal to record the error when link
training. To make sure Lane Error Status is correct in OS runtime,
add a Kconfig PCIEXP_LANE_ERR_STAT_CLEAR that clears the PCIe lane error
status register at the end of PCIe link training.
