Just so you know, the amount of support on the RPi4 you might be able to get
updating bcm2835_defconfig's config is very limited. Only 1GB of ram and no
PCIe (so no USBs).

FYI I've been working on getting a workable configuration for arm32, short of
creating a new config altogether:

That said, if you insist on booting with bcm2835_defconfig, I have no problem
with the patch.

Regards,
Nicolas
