I did the following experiment mostly just to observe
the current status for sysutils/u-boot-rpi4 based
booting of the RPi4 (with rather modern RPi4 firmware
in use). (I normally use uefi/acpi instead of u-boot,
uefi now at v1.17 . I was hoping to see if u-boot based
also had a bug that uefi contexts have.)
With the kernel on the microsd card (and earlier stage
materials), boot -v reported (before mounting / from
USB3 became relevant):
pci1: <PCI bus> on pcib1
pcib1: allocated bus range (1-1) for rid 0 of pci1
pci1: domain=3D0, physical bus=3D1

simplebus2: <xhci@7e9c0000> mem 0x7e9c0000-0x7eabffff irq 78 disabled =

So the USB3 ends up unavailable.
/ would have been from a USB3 SSD if things had worked.
