RPi 4B with 1 or 8 GiB RAM does not boot

[troglobit]

Current Behavior

For certain new models of Raspberry Pi 4B, in particular 1 GiB and 8 GiB, we've seen problems where the BootROM doesn't even load u-boot.bin (the "kernel"):

Isn't this fixed with:

commit 19471dd95e9abf77810854c2e033192935ef357a

    buildroot: bump rpi-firmware version to 95be71b
    
    Newer board revisions of RPi4 and CM4, as well as older boards with
    upgraded EEPROM, require newer firmware.
    
    This is a backport of the latest rpi-firmware on Buildroot master.

Yes, we added the issue after the fact and I've just not gotten around to updating the ChangeLog.
