From 8f29b1573ddf3b7ed7c53bee1a7d55e574806205 Mon Sep 17 00:00:00 2001 From: Mathew McBride Date: Wed, 24 Feb 2021 04:53:40 +0000 Subject: [PATCH] grub2: enable EFI for armvirt This adds a separate package for EFI on Arm SystemReady compatible machines. 32-bit Arm UEFI is supported as well. It is very similar to x86-64 EFI setup, without the need for BIOS backward compatibility and slightly different default modules.
