PCI: dwc: Add Baikal-T1 PCIe controller support
Baikal-T1 SoC is equipped with DWC PCIe v4.60a host controller. It can be
trained to work up to Gen.3 speed over up to x4 lanes. The host controller
is attached to the DW PCIe 3.0 PCS via the PIPE-4 interface, which in its
turn is connected to the DWC 10G PHY. The whole system is supposed to be
fed up with four clock sources: DBI peripheral clock, AXI application
clocks and external PHY/core reference clock generating the 100MHz signal.
In addition to that the platform provide a way to reset each part of the
controller: sticky/non-sticky bits, host controller core, PIPE interface,
PCS/PHY and Hot/Power reset signal. The driver also provides a way to
handle the GPIO-based PERST# signal.
Note due to the Baikal-T1 MMIO peculiarity we have to implement the DBI
interface accessors which make sure the IO operations are dword-aligned.

PCI: qcom-ep: Add Qualcomm PCIe Endpoint controller driver
Add driver for Qualcomm PCIe Endpoint controller based on the DesignWare
core with added Qualcomm-specific wrapper around the core. The driver
support is very basic such that it supports only enumeration, PCIe
read/write, and MSI. There is no ASPM and PM support for now but these will
be added later.
The driver is capable of using the PERST# and WAKE# side-band GPIOs for
operation and written on top of the DWC PCI framework.

PCI: tegra194: Fix MCFG quirk build regressions
7f100744749e ("PCI: tegra: Add Tegra194 MCFG quirks for ECAM errata")
caused a few build regressions:
- 7f100744749e removed the Makefile rule for CONFIG_PCIE_TEGRA194, so
pcie-tegra.c can no longer be built as a module. Restore that rule.
- 7f100744749e added "#ifdef CONFIG_PCIE_TEGRA194" around the native
driver, but that's only set when the driver is built-in (for a module,
CONFIG_PCIE_TEGRA194_MODULE is defined).
The ACPI quirk is completely independent of the rest of the native
driver, so move the quirk to its own file and remove the #ifdef in the
native driver.
- 7f100744749e added symbols that are always defined but used only when
CONFIG_PCIEASPM, which causes warnings when CONFIG_PCIEASPM is not set:
drivers/pci/controller/dwc/pcie-tegra194.c:259:18: warning: ‘event_cntr_data_offset’ defined but not used [-Wunused-const-variable=]

PCI: tegra: Add Tegra194 MCFG quirks for ECAM errata
The PCIe controller in Tegra194 SoC is not ECAM-compliant. With the
current hardware design, ECAM can be enabled only for one controller (the
C5 controller) with bus numbers starting from 160 instead of 0. A different
approach is taken to avoid this abnormal way of enabling ECAM for just one
controller but to enable configuration space access for all the other
controllers. In this approach, ops are added through MCFG quirk mechanism
which access the configuration spaces by dynamically programming iATU
(internal AddressTranslation Unit) to generate respective configuration
accesses just like the way it is done in DesignWare core sub-system.
This issue is specific to Tegra194 and it would be fixed in the future
generations of Tegra SoCs.

PCI: Avoid building empty drivers

PCI: Avoid building empty drivers
There are harmless warnings when compile testing the kernel with
CONFIG_TRIM_UNUSED_KSYMS:
drivers/pci/controller/dwc/pcie-al.o: no symbols
drivers/pci/controller/pci-thunder-ecam.o: no symbols
drivers/pci/controller/pci-thunder-pem.o: no symbols
The problem here is that the host drivers get built even when the
configuration symbols are all disabled, as they pretend to not be drivers
but are silently enabled because of the promise that ACPI-based systems
need no drivers.
Add back the normal symbols to have these drivers built, and change the
logic to otherwise only build them when both CONFIG_PCI_QUIRKS and
CONFIG_ACPI are enabled.
As a side-effect, this enables compile-testing the drivers on other
architectures, which in turn needs the acpi_get_rc_resources() function to
be defined.

PCI: al: Add Amazon Annapurna Labs PCIe host controller driver
Add driver for Amazon's Annapurna Labs PCIe host controller. The
controller is based on DesignWare's IP.
The controller doesn't support accessing the Root Port's config space via
ECAM, so we obtain its base address via an AMZN0001 device.
Furthermore, the DesignWare PCIe controller doesn't filter out config
transactions sent to devices 1 and up on its bus, so they are filtered by
the driver.
All subordinate buses do support ECAM access.
Implementing specific PCI config access functions involves:
- Adding an init function to obtain the Root Port's base address from
an AMZN0001 device.
- Adding a new entry in the MCFG quirk array.
[bhelgaas: Note that there is no Kconfig option for this driver because it
is only intended for use with the generic ACPI host bridge driver. This
driver is only needed because the DesignWare IP doesn't completely support
ECAM access to the root bus.]

PCI: Collect all native drivers under drivers/pci/controller/
Native PCI drivers for root complex devices were originally all in
drivers/pci/host/. Some of these devices can also be operated in endpoint
mode. Drivers for endpoint mode didn't seem to fit in the "host"
directory, so we put both the root complex and endpoint drivers in
per-device directories, e.g., drivers/pci/dwc/, drivers/pci/cadence/, etc.
These per-device directories contain trivial Kconfig and Makefiles and
clutter drivers/pci/. Make a new drivers/pci/controllers/ directory and
collect all the device-specific drivers there.
No functional change intended.

Add support to PCIe RC controller on Intel Gateway SoCs.
PCIe controller is based of Synopsys DesignWare PCIe core.
Intel PCIe driver requires Upconfigure support, Fast Training
Sequence and link speed configurations. So adding the respective
helper functions in the PCIe DesignWare framework.
It also programs hardware autonomous speed during speed
configuration so defining it in pci_regs.h.
Also, mark Intel PCIe driver depends on MSI IRQ Domain
as Synopsys DesignWare framework depends on the
PCI_MSI_IRQ_DOMAIN.
