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 32-bit and 64-bit system builds and some related fixes and updates in the usb/xhci and the pci driver core code.
This iteration includes minor corrections in patches 7, 9, 10 addressing review comments.
The patch series is based on v2020.07-rc1 tree.
Thanks, Sylwester
