Please don't forget about this series. The new 8GB RPi4 contains this HW design
change and USB will not work without it. See this discussion on the downstream
kernel github, where other OS/bootloaders are hitting the issue:
https://github.com/raspberrypi/firmware/issues/1402
Otherwise, the Linux version of this is already in linux-next:
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/usb/host/pci-quirks.c?h=next-20200529&id=c65822fef4adc0ba40c37a47337376ce75f7a7bc
