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
separately.
This iteration includes mostly correction in the PCIe controller driver
patch addressing Simon's review comments. Hopefully I have addressed
all comments. I didn't decide to use struct for the control registers
as the registers offsets used are sparse and I don't have detailed
documentation of the hardware to be able to define the struct accurately.
The patch series is based on v2020.07-rc1 tree.
Thanks,
Sylwester
