Scripts for building a talos image

A couple of scripts needed for build a talos image, mainly for create custom images and trying out patched for u-boot or the kernel.

It is current set up for to build arm64 architecture images from a amd64 host, so make sure you do a:

sudo apt install gcc-aarch64-linux-gnu

1. Run a registry

   first we run a registry images are pushed to this registry and the talos image will be build using our custom containers.

   docker run --rm -p 5000:5000 --name registry registry:2

2. Build and push a u-boot image

   `Here u-boot next branch is used, talos obviously uses a u-boot release.

   cd u-boot
   ./doall

   When succesfull you should see a "PUT /v2/ubootbash/manifests/latest HTTP/1.1" call to your docker registry, takes about a minute on my machine, all good. `

3. Build and push a kernel image

   Currently the doall script applies this patch to mitigate this issue.

   cd pkgs
   ./doall

   get a lot of coffee.

   When succesfull you should see a "PUT /v2/tlarsen/kernel/manifests/v1.5.0-9-g7f9d6eb-dirty HTTP/1.1" in your registry log.

4. Build a talos image

   The Dockerfile is patched so it uses the u-boot and kernel images.

   cd talos
   ./doall

   get some coffee.
