1ed6648be0 x86: Reserve PCIe ECAM address range in the E820 table
We should mark PCIe ECAM address range in the E820 table as reserved
otherwise kernel will not attempt to use ECAM.

53832bb8d6 x86: mpspec: Move writing ISA interrupt entry after PCI
On some platforms the I/O APIC interrupt pin#0-15 may be connected
to platform pci devices' interrupt pin. In such cases the legacy ISA
IRQ is not available so we should not write ISA interrupt entry if
it is already occupied.

d11d9ef157 dm: pci: Support bridge device configuration correctly
Commit aec241d "dm: pci: Use the correct hose when configuring devices"
was an attempt to fix pci bridge device configuration, but unfortunately
that does not work 100%. In pciauto_config_devices(), the fix tried to
call pciauto_config_device() with a ctlr_hose which is supposed to be
the root controller hose, however when walking through a pci topology
with 2 or more pci bridges this logic simply fails.

The call chain is: pciauto_config_devices()->pciauto_config_device()
->dm_pci_hose_probe_bus(). Here the call to dm_pci_hose_probe_bus()
does not make any sense as the given hose is not the bridge device's
hose, instead it is either the root controller's hose (case#1: if it
is the 2nd pci bridge), or the bridge's parent bridge's hose (case#2:
if it is the 3rd pci bridge). In both cases the logic is wrong.

For example, for failing case#1 if the bridge device to config has the
same devfn as one of the devices under the root controller, the call
to pci_bus_find_devfn() will return the udevice of that pci device
under the root controller as the bus, but this is wrong as the udevice
is not a bus which does not contain all the necessary bits associated
with the udevice which causes further failures.

To correctly support pci bridge device configuration, we should still
call pciauto_config_device() with the pci bridge's hose directly.
In order to access valid pci region information, we need to refer to
the root controller simply by a call to pci_bus_to_hose(0) and get the
region information there in the pciauto_prescan_setup_bridge(),
pciauto_postscan_setup_bridge() and pciauto_config_device().

8326f136da dm: pci: Pass only device/function to pci_bus_find_devfn()
In dm_pci_hose_probe_bus(), pci_bus_find_devfn() is called with a bdf
which includes a bus number, but it really should not as this routine
only expects a device/function encoding.

4d8615cbf5 dm: pci: Use complete bdf in all pci config read/write routines
Currently pci_bus_read_config() and pci_bus_write_config() are
called with bus number masked off in the parameter bdf, and bus
number is supposed to be added back in the bridge driver's pci
config read/write ops if the device is behind a pci bridge.
However this logic only works for a pci topology where there is
only one bridge off the root controller. If there is addtional
bridge in the system, the logic will create a non-existent bdf
where its bus number gets accumulated across bridges.

To correct this, we change all pci config read/write routines
to use complete bdf all the way up to the root controller.

95f3aa209a dm: pci: Correct primary/secondary/subordinate bus number assignment
In driver model, each pci bridge device has its own hose structure.
hose->first_busno points to the bridge device's device number, so
we should not substract hose->first_busno before programming the
bridge device's primary/secondary/subordinate bus number registers.
