Hi all,

This patch series adds USB host support for Raspberry Pi 4 board. 
It includes the Broadcom STB PCIe driver ported from Linux kernel,
a memory mapping update for the xHCI controller behind a PCIe bridge
for 32-bit and 64-bit system builds and some related fixes and updates
in the usb/xhci and the pci core code.

Any changes since previous (RFC) version are listed in individual 
patches.  The most significant change was rewriting the PCIe driver 
to align with current mainline Linux kernel version.  As suggested, 
readq/writeq have been removed from xhci_{readq/writeq} helpers 
instead of adding a Kconfig option.

This patch series is based on v2020.04 tag.

Regards,
Sylwester

  rpi4: shorten a mapping for the DRAM
  rpi4: add a mapping for the PCIe XHCI controller MMIO registers (ARM
    64bit)
  rpi4: add a mapping for the PCIe XHCI controller MMIO registers (ARM
    32bit)
  config: Enable support for the XHCI controller on RPI4 board

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
    initialization
  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 STB PCIe controller
