v0.8.0

This is a major Buildroot and Linux update. It should be seamless for most
0.7.0 users.

• Changes

  • Refresh ramoops-overlay.dts. This actually changes the default pstore
    settings to reserve less DRAM based on experience of not needing nearly as
    much. Settings can be overridden now via the config.txt.
  • Use EEx to generate the fwup.conf. This removes a lot of repetition. If
    you've made a custom fwup.conf, please review git commit log for details.
  • Add 5" Raspberry Pi Touch Display overlay
