Binary package “grub-uboot-bin” in ubuntu focal

GRand Unified Bootloader, version 2 (ARM U-Boot modules)

 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 package contains GRUB modules that have been built for use with ARM
 systems with U-Boot. It can be installed in parallel with other flavours,
 but will not automatically install GRUB as the active boot loader nor
 automatically update grub.cfg on upgrade unless grub-uboot is also
 installed.
