Update:
While the bug in question is not a FreeBSD-specific issue, I figured
that I would share this update for anyone who might benefit.
I have built U-Boot from the ports tree (sysutils/u-boot-rpi4) with the
following changes:
files/rpi4_fragment:
* *CONFIG_USB=n*
* *CONFIG_USB_HOST=n*
* *CONFIG_USB_STORAGE=n*
* *CONFIG_USB_XHCI_PCI=n*
* *CONFIG_USB_XHCI_HCD=n**
*
* *CONFIG_CMD_USB=n*
U-Boot gives an error message regarding the unavailable 'usb' command
since it's been disabled and I didn't remove a reference to it from the
startup script, but it booted up anyway.
This workaround prevents the bug (if you don't use a USB boot device)
while I wait for some feedback from the U-Boot project maintainers.

I confirmed that this particular USB device, being self-powered,
is not pulling a current on the pi's USB port. I think this rules
out a voltage problem.
<br>
<br>
The U-Boot interactive shell still shows the MMC device, but
refuses to boot from it under these conditions. The one-liner
workaround you mentioned is unfortunately not resolving this
problem.
<br>
<br>
Until I can find time to try fixing the bug, I am building U-Boot
without support for USB storage devices and network booting, since
I don't need those features at this time. I'll let you know if
that works.

The problem is not limited or specific to FreeBSD's use of

U-Boot. For example, demonstrated with Fedora 33 and some
