Hi all,

This patch series adds USB host support for Raspberry Pi 4 board. 
It includes the Broadcom STB PCIe controller driver ported from Linux 
kernel, a memory mapping update for the xHCI controller on PCIe bus
for 64-bit builds and some related fixes and updates in the usb/xhci 
and the pci driver core code.

The 32-bit ARM part has be excluded from the series and will be posted

The difference comparing to previous version is only in the config update
patch "configs: Enable support for the XHCI controller on RPI4 board (ARM

The patch series is based on v2020.07-rc1 tree.


Marek Szyprowski (3):
  rpi4: shorten a mapping for the DRAM
  rpi4: add a mapping for the PCIe XHCI controller MMIO registers (ARM
  configs: Enable support for the XHCI controller on RPI4 board (ARM

Nicolas Saenz Julienne (1):
  linux/bitfield.h: Add primitives for manipulating bitfields both in
    host- and fixed-endian

Sylwester Nawrocki (5):
  usb: xhci: Add missing cache flush in the scratchpad array
  usb: xhci: Use only 32-bit accesses in xhci_writeq/xhci_readq
  pci: Move some PCIe register offset definitions to a common header
  pci: Add some PCI Express capability register offset definitions
  pci: Add driver for Broadcom BCM2711 SoC PCIe controller
