migrate the nix install to an external USB drive. this requires a patch to uboot: - uboot thinks the drive has a capacity of 0 (i.e. 'unknown'). unclear precisely why. could be noncompliant drive firmware, or a timeout somewhere. and a patch to the rpi bootloader: - in order to trampoline into the rpi-4 uboot. and custom kernel modules in the initrd: - in order to detect the USB hub (rpi fw). additionally, i'm MANUALLY placing `bcm2711-rpi-400.dtb` into `/boot/nixos/..-linux-5.10.111-dtbs/broadcom`. i'll want to do this automatically over time. i hope to simplify much of this over time: this is just the first thing which works after a couple days of hacking at it. 2022-05-17 01:58:12 +00:00			`{ pkgs }:`

uboot: split the patches apart and disable the verbose logging logging still has some verbosity. i may turn it down further. 2022-05-17 09:10:26 +00:00			`./01-skip-lba-check.patch`
