v1.2.0

• New features
  • Buildroot 2018.05
  • boardid 1.1.0
  • bborg-overlays (latest SHA)

Buildroot 2018.05 contains the normal set of minor version bumps throughout. It
let us remove 8 patches that we had been carrying around. See the Buildroot
announcement
for details.

The boardid bump improves about the U-boot environment block support by
simplifying the configuration needed in the erlinit.config script.

The bborg-overlays project has had several improvements since we last took a
snapshot of it. Some of these are needed for the upcoming device tree overlay
support in nerves_system_bbb that uses the new U-boot overlay support.
