PCI: faraday: Add Faraday Technology FTPCI100 PCI Host Bridge driver Add a host bridge driver for the Faraday Technology FPPCI100 host bridge, used for Cortina Systems Gemini SoC (SL3516) PCI Host Bridge. This code is inspired by the out-of-tree OpenWRT patch and then extensively rewritten for device tree and using the modern helpers to cut down and modernize the code to all new PCI frameworks. A driver exists in U-Boot as well. Tested on the ITian Square One SQ201 NAS with the following result in the boot log (trimmed to relevant parts): OF: PCI: host bridge /soc/pci@50000000 ranges: OF: PCI: IO 0x50000000..0x500fffff -> 0x00000000 OF: PCI: MEM 0x58000000..0x5fffffff -> 0x58000000 ftpci100 50000000.pci: PCI host bridge to bus 0000:00 pci_bus 0000:00: root bus resource [bus 00-ff] pci_bus 0000:00: root bus resource [io 0x0000-0xfffff] pci_bus 0000:00: root bus resource [mem 0x58000000-0x5fffffff] ftpci100 50000000.pci: DMA MEM1 BASE: 0x0000000000000000 -> 0x0000000007ffffff config 00070000 ftpci100 50000000.pci: DMA MEM2 BASE: 0x0000000000000000 -> 0x0000000003ffffff config 00060000 ftpci100 50000000.pci: DMA MEM3 BASE: 0x0000000000000000 -> 0x0000000003ffffff config 00060000 PCI: bus0: Fast back to back transfers disabled pci 0000:00:00.0: of_irq_parse_pci() failed with rc=-22 pci 0000:00:0c.0: BAR 0: assigned [mem 0x58000000-0x58007fff] pci 0000:00:09.2: BAR 0: assigned [mem 0x58008000-0x580080ff] pci 0000:00:09.0: BAR 4: assigned [io 0x1000-0x101f] pci 0000:00:09.1: BAR 4: assigned [io 0x1020-0x103f] pci 0000:00:09.0: enabling device (0140 -> 0141) pci 0000:00:09.0: HCRESET not completed yet! pci 0000:00:09.1: enabling device (0140 -> 0141) pci 0000:00:09.1: HCRESET not completed yet! pci 0000:00:09.2: enabling device (0140 -> 0142) rt61pci 0000:00:0c.0: enabling device (0140 -> 0142) ieee80211 phy0: rt2x00_set_chip: Info - Chipset detected - rt: 2561, rf: 0003, rev: 000c ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver ehci-pci: EHCI PCI platform driver ehci-pci 0000:00:09.2: EHCI Host Controller ehci-pci 0000:00:09.2: new USB bus registered, assigned bus number 1 ehci-pci 0000:00:09.2: irq 125, io mem 0x58008000 ehci-pci 0000:00:09.2: USB 2.0 started, EHCI 1.00 hub 1-0:1.0: USB hub found hub 1-0:1.0: 4 ports detected uhci_hcd: USB Universal Host Controller Interface driver uhci_hcd 0000:00:09.0: UHCI Host Controller uhci_hcd 0000:00:09.0: new USB bus registered, assigned bus number 2 uhci_hcd 0000:00:09.0: HCRESET not completed yet! uhci_hcd 0000:00:09.0: irq 123, io base 0x00001000 hub 2-0:1.0: USB hub found hub 2-0:1.0: config failed, hub doesn't have any ports!

PCI: iproc: Add iProc PCIe MSI support Add PCIe MSI support for both PAXB and PAXC interfaces on all iProc-based platforms. The iProc PCIe MSI support deploys an event queue-based implementation. Each event queue is serviced by a GIC interrupt and can support up to 64 MSI vectors. Host memory is allocated for the event queues, and each event queue consists of 64 word-sized entries. MSI data is written to the lower 16-bit of each entry, whereas the upper 16-bit of the entry is reserved for the controller for internal processing. Each event queue is tracked by a head pointer and tail pointer. Head pointer indicates the next entry in the event queue to be processed by the driver and is updated by the driver after processing is done. The controller uses the tail pointer as the next MSI data insertion point. The controller ensures MSI data is flushed to host memory before updating the tail pointer and then triggering the interrupt. MSI IRQ affinity is supported by evenly distributing the interrupts to each CPU core. MSI vector is moved from one GIC interrupt to another in order to steer to the target CPU. Therefore, the actual number of supported MSI vectors is: M * 64 / N where M denotes the number of GIC interrupts (event queues), and N denotes the number of CPU cores. This iProc event queue-based MSI support should not be used with newer platforms with integrated MSI support in the GIC (e.g., giv2m or gicv3-its).

# They contain MCFG quirks to replace the generic ECAM accessors with
# device-specific ones that are shared with the DT driver.
# The ACPI driver is generic and should not require driver-specific
# config options to be enabled, so we always build these drivers on
# ARM64 and use internal ifdefs to only build the pieces we need
# depending on whether ACPI, the DT driver, or both are enabled.
