24d25dbfa6 x86/PCI: amd: factor out MMCONFIG discovery
This factors out the AMD native MMCONFIG discovery so we can use it
outside amd_bus.c.

amd_bus.c reads AMD MSRs so it can remove the MMCONFIG area from the
PCI resources.  We may also need the MMCONFIG information to work
around BIOS defects in the ACPI MCFG table.

7ec303a724 xtensa/PCI: convert to pci_scan_root_bus() for correct root bus resources
Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus
fixups.  This fixes the problem of "early" and "header" quirks
seeing incorrect root bus resources.

This arch was unusual because it filled in bus->resource[0..3] in
pcibios_init(), then overwrote them, applied io_space.offset and
checked for unset resources in pcibios_fixup_bus().  I moved all of
that to a new pci_controller_apertures() that we can use before
scanning the root bus.

2cd6975a4f x86/PCI: convert to pci_create_root_bus() and pci_scan_root_bus()
x86 has two kinds of PCI root bus scanning:

(1) ACPI-based, using _CRS resources.  This used pci_create_bus(), not
    pci_scan_bus(), because ACPI hotplug needed to split the
    pci_bus_add_devices() into a separate host bridge .start() method.

    This patch parses the _CRS resources earlier, so we can build a list of
    resources and pass it to pci_create_root_bus().

    Note that as before, we parse the _CRS even if we aren't going to use
    it so we can print it for debugging purposes.

(2) All other, which used either default resources (ioport_resource and
    iomem_resource) or information read from the hardware via amd_bus.c or
    similar.  This used pci_scan_bus().

    This patch converts x86_pci_root_bus_res_quirks() (previously called
    from pcibios_fixup_bus()) to x86_pci_root_bus_resources(), which builds
    a list of resources before we call pci_scan_root_bus().

    We also use x86_pci_root_bus_resources() if we have ACPI but are
    ignoring _CRS.

46fbade05c x86/PCI: use pci_scan_bus() instead of pci_scan_bus_parented()
This doesn't change any functionality, but it makes a subsequent patch
slightly simpler.

pci_scan_bus(NULL, ...) and pci_scan_bus_parented() are identical except
that pci_scan_bus() also calls pci_bus_add_devices():

  pci_scan_bus_parented
    pci_create_bus
    pci_scan_child_bus

  pci_scan_bus
    pci_create_bus
    pci_scan_child_bus
    pci_bus_add_devices

All callers of pcibios_scan_root() call pci_bus_add_devices() explicitly,
and we don't pass a parent device, so we might as well use pci_scan_bus().

6361d72b04 x86/PCI: read Broadcom CNB20LE host bridge info before PCI scan
We currently read the CNB20LE aperture information in a PCI quirk,
which happens after we've already created the root bus.  This patch
changes it to read the apertures earlier so we can create the root
bus with the correct resources.

I believe the CNB20LE lives at "pci 0000:00:00" based on

4723b984b2 microblaze/PCI: use pci_scan_root_bus()
Microblaze doesn't need to replace pci_scan_child_bus() or do anything
special before pci_bus_add_devices(), so we can use the more generic PCI
path in pci_scan_root_bus().

58de74b805 microblaze/PCI: convert to pci_create_root_bus() for correct root bus resources
Convert from pci_create_bus() to pci_create_root_bus().  This way the root
bus resources are correct immediately.  This patch doesn't fix a problem
because microblaze fixed the resources before scanning the bus, but it makes
microblaze more consistent with other architectures.  It also allows us to
use the pci_scan_root_bus() path safely.

We can't use pci_scan_root_bus() because, like x86, ACPI hotplug currently
requires pci_bus_add_devices() in a separate host bridge .start() method.

Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus
resource fixups.  This fixes the problem of "early" and "header" quirks
seeing incorrect root bus resources.

Note that peer root buses are scanned with pci_scan_bus() (which is now
deprecated), so they have the default ioport_resource and iomem_resource
resources.  This is unchanged from before, but these resources are
incorrect, and I don't know how to discover the correct ones.

ca3671a833 x86/PCI: amd: Kill misleading message about enablement of IO access to PCI ECS]
Commit 24d9b70b8c679264756a6980e668b96b3f964826 (x86: Use PCI method
for enabling AMD extended config space before MSR method) added a
message when IO access to PCI ECS was enabled via access to the NB_CFG
PCI register.  This can lead to a bogus message like

[    0.365177] Extended Config Space enabled on 0 nodes

which is misleading because IO ECS access is subsequently enabled for
AMD CPUs (that support this) by modifying the corresponding NB_CFG
MSR.

Furthermore it's not "Extended Config Space" that is enabled by this
register setting. It's the IO access that is enabled for extended
configruation space.

IMHO the ambiguous message needs to be cancelled.

96c5590058 PCI: Pull PCI 'latency timer' setup up into the core
The 'latency timer' of PCI devices, both Type 0 and Type 1,
is setup in architecture-specific code [see: 'pcibios_set_master()'].
There are two approaches being taken by all the architectures - check
if the 'latency timer' is currently set between 16 and 255 and if not
bring it within bounds, or, do nothing (and then there is the
gratuitously different PA-RISC implementation).

There is nothing architecture-specific about PCI's 'latency timer' so
this patch pulls its setup functionality up into the PCI core by
creating a generic 'pcibios_set_master()' function using the '__weak'
attribute which can be used by all architectures as a default which,
if necessary, can then be over-ridden by architecture-specific code.

No functional change.

9cdce18d6f PCI: Xtensa: convert pcibios_set_master() to a non-inlined function
This patch converts Xtensa's architecture-specific

allow follow on patches to create a generic 'pcibios_set_master()'
function using the '__weak' attribute which can be used by all
architectures as a default which, if necessary, can then be over-
ridden by architecture-specific code.

Converting 'pci_bios_set_master()' to a non-inlined function will
allow Xtensa's 'pcibios_set_master()' implementation to remain
architecture-specific after the generic version is introduced and
thus, not change current behavior.
