 You know it was me, and I did it because it was crap.

 This is not what I'm talking about.

 Again not what I'm talking about.

 Again not what I'm talking about.

 I know (or at least hope) that you're trying to help, so let's start
2021 on a good base.
 Here I'm talking about u-boot itself, not FreeBSD, not booting from
USB on the RPI4, U-Boot, only U-Boot.
 Right now, using the latest taggued release of rpi-firmware
(20201201), there is no raspberrypi,firmware-reset compatible node in
the dtb so U-Boot cannot init the usb controller. That doesn't mean
that the RPI cannot boot from usb, it can and will load u-boot, but
when u-boot will look for it's "root device" (the usb drive) this will
fail as the usb controller couldn't be init.
 This also means that when we boot from SD card, we cannot access usb
drives from U-Boot, as, again, the usb controller wasn't init.
