== ~~QEMU~~ support ==

== NixOS "support" for board-specific kernels or bootloaders ==

As of ~~June 2016~~, the ~~versatile build of~~ u-boot isn't ~~built anymore~~.

I re-worked the introduction paragraph of the article, but I have added a partly unfounded remark about NixOS being able to work with specific kernels or bootloaders. The remark is built on the fact that there is [https://github.com/NixOS/nixpkgs/blob/0676d691724b2ceebde17377fddf9bc7fcf8f5b0/nixos/modules/installer/cd-dvd/sd-image-raspberrypi.nix a raspberry pi specific image using a specific kernel], that [https://github.com/NixOS/nixpkgs/issues/29569#issuecomment-347023896 it is possible to use upstream forks with fixes for the kernel]. There is no documentation yet on how to use a vendor fork (e.g. allwinner non-upstream fork) for the kernel or u-boot, and no documentation on how to boot NixOS when extlinux support isn't present in the u-boot build.

~~Furthermore~~, ~~the pre-built image is not present anymore on the mirror.~~

~~U-Boot: Drop Versatile build~~

~~I had broken this at some point and the patch conflicts quite often.~~

== Latest u-boot builds form Hydra ==

~~Hopefully soon the Raspberry Pi 2 emulation in QEMU can be used instead.~~

This isn't perfect, but fresh from nixpkgs-unstable.

== Distributed Builds ==

I've added a short section about using an aarch64 remote builder to speed up builds for armv6l and armv7l (With the advent of the raspberry pi 4, this is probably a relatively convenient way to run nixos on the raspberry pi 1 / raspberry pi zero(w) without suffering very long build times). It might make sense to merge it with the section on cross-compiling with qemu, which also mentions distributed builds briefly, but I wasn't sure how best to do it.

== Option boot.loader.grub.devices ==

I am currently trying to setup a Raspberry Pi and neither on the ARM installation page, the default configuration, nor this page here, does the required option "boot.loader.grub.devices" come up.

With my configuration, the system requires me to set this.

This is my configuration: https://gist.github.com/ShalokShalom/f5b190f531d354614a7319a7f3d22fc1
