* Backport USB PCIe/XHCI patches to U-Boot 2020.07 Backport relevant patches required to make PCIe/USB XHCI work. * Backport/integrate PCIe device tree changes from upstream Linux U-Boot uses the device tree provided by upstream Linux. Make sure the device tree has the relevant chanages to make VL805 USB controller reset work. * Document RPi 4 USB mass storage support (#746)

Subject: [PATCH 20/20] config: Enable support for the XHCI controller on RPI4
|
|
board
|
|
|
|
This requires enabling BRCMSTB PCIe and XHCI_PCI drivers as well as PCI
|
|
and USB commands. To get it working one has to call the following commands:
|
|
"pci enum; usb start;", thus such commands have been added to the default
|
|
"preboot" environment variable. One has to update their environment if it
|
|
is already configured to get this feature working out of the box.
