grub-ieee1275 2.04-1ubuntu26.6 (ppc64el binary) in ubuntu focal

 GRUB is a portable, powerful bootloader. This version of GRUB is based on a
 cleaner design than its predecessors, and provides the following new features:
 .
  - Scripting in grub.cfg using BASH-like syntax.
  - Support for modern partition maps such as GPT.
  - Modular generation of grub.cfg via update-grub. Packages providing GRUB
    add-ons can plug in their own script rules and trigger updates by invoking
    update-grub.
 .
 This is a dependency package for a version of GRUB that has been built for
 use with Open Firmware implementations. Installing this package indicates
 that this version of GRUB should be the active boot loader.
