== Justification ==
The console font size on a high resolution screen is only suitable for
eagles, although we can choose a bigger font by running:
  sudo dpkg-reconfigure console-setup

But that is not enough, the font size before video driver kicks in is
still small. If we need to debug some early stage issues that will be a

== Fix ==
ac8b6f14 (Fonts: New Terminus large console font)
Config for this TER16x32 and the compiled-in fonts support needs to be
enabled to keep engineers away from ophthalmologists.

* Disco
  It's already there. Just need to enable the configs.
* Cosmic / Bionic
  Patch can be cherry-picked.
* Xenial
  It needs an extra patch to make it a clean cherry-pick:
  * 7bcae826 (lib/fonts/Kconfig: keep non-Sparc fonts listed together
* Trusty
  It needs two extra patches to make it a clean cherry-pick:
  * fonts: Add 6x10 font (33ac9dba)
  * lib/fonts/Kconfig: keep non-Sparc fonts listed together (7bcae826).
  And a config entry for the 6x10 font.

Commit "fonts: Add 6x10 font" is just adding a new font.
Commit "lib/fonts/Kconfig: keep non-Sparc fonts listed together" is
just a patch for context rearrangement.

I think these two are safe to be pulled-in.

== Test ==
Test kernels: http://people.canonical.com/~phlin/kernel/lp-1819881-font/

Add "fbcon=font:TER16x32" to the GRUB_CMDLINE_LINUX in
/etc/default/grub, and follow these steps.

* Disco
  sudo update-grub; sudo reboot
* Cosmic / Bionic
  Add "GRUB_GFXPAYLOAD_LINUX=3840x2160" to /etc/default/grub
  sudo update-grub; sudo reboot
* Xenial
  sudo update-grub; sudo reboot
* Trusty
  sudo update-grub; sudo reboot (I need the proprietary nvidia driver
  to boot for my SUT - Dell Precision M3800)

The font before the video driver kicks in will get bigger.

== Regression potential ==
Minimal, changes are limited to adding console fonts, turn on fonts
related kernel configs.
