This series adds support for the later. Note that there are a set of constraints we have to consider (some of them I missed on v1): - We need to make sure the VideoCore firmware interface is up and running before running the VL805 firmware load call. - There is no way to discern RPi4's VL805 chip from other platforms', so we need the firmware load to happen *before* running quirk_usb_handoff_xhci(). Failure to do so results in an unwarranted 5 second wait while the fixup code polls xHC's unexisting state. --- Changes since v5: - Fix issues reported by Kbuild test robot Changes since v4: - Addressed Sergei's comments - Fix potential warning in patch #2 Changes since v3: - Addressed Greg's comments There was no v2, my bad.
