fffc9f3b9d device/pci: Declare pci_root_bus()
This is used a lot, cache the result so search
of domain from devicetree is only done once.

Improvement only applies when MAYBE_STATIC evaluates
to static.

cd49cce7b7 coreboot: Replace all IS_ENABLED(CONFIG_XXX) with CONFIG(XXX)
This patch is a raw application of

 find src/ -type f | xargs sed -i -e 's/IS_ENABLED\s*(CONFIG_/CONFIG(/g'

db866ba200 amdfam10 boards: Fix regression on dev_find_slot() removal
For these platforms, the first PCI node on devicetree
is not the root of PCI bus hierarchy, and the topology
(bus->children and dev->sibling links) are getting
manipulated during HyperTransport enumeration.

This workaround reverts back to old dev_find_slot() with
its bad semantics.

ad7674ed00 device: Introduce pcidev_on_root() and friends
Semantics of dev_find_slot() are ill in the sense that
it only works after device enumeration has completed in
ramstage. Plan is to declare it as deprecated.

Introduce pcidev_on_root() and pcidev_path_on_root()
functions to replace cases where this was called with
static argument bus == 0. New implementation only walks
the root bus of the PCI tree, while old one walked
the entire linked list of devices.

Introduce pcidev_path_behind() to replace cases where
argument bus != 0. The required parent node is typically
one of the PCIe root functions that you locate using
pcidev_on_root() above.

New forms are safe to use with early devicetree and
before PCI bus numbers have been assigned.

a0dabd1848 device: add child traversal helper function
Add a function, dev_bus_each_child(), which walks through all the
children for a given bus of a device. This helper allows one to
walk through all the children of a given device's bus.

81ec9c0500 device: Rename device_simple.c --> device_const.c
In early stages (pre ramstage), we have two notions of devices.
To access the hardware, "simple device" handles are used. These
are plain numbers. To access the static information of the device
tree, we use `struct device` pointers. This is referred to as
DEVTREE_EARLY in the code.

This file is about the latter and its name reflects that the
tree remains unmodified.
