This supports powering up the device (using an external tool you provide based on your particular lab), talking over serial to wait for the fastboot prompt, and then booting a fastboot image on a target device. I was previously relying on LAVA for this, but that ran afoul of corporate policies related to the AGPL. However, LAVA wasn't doing too much for us, given that gitlab already has a job scheduler and tagging and runners. We were spending a lot of engineering on making the two systems match up, when we can just have gitlab do it directly. Lightly-reviewed-by: Kristian H.

# Tiny script to read bytes from serial, and write the output to stdout, with a
|
|
# buffer in between so we don't lose serial output from its buffer.
|
|
#
|
|
# We don't use 'cu' because it requires stdin to be hooked up and I never
|
|
# managed to make that work without getting blocked somewhere. We don't use
|
|
# 'conserver' because it's non-free.
