[fedora-arm] Re: Status of armhfp grubs2-efi on top of Uboot

Hey,

Sorry about the late reply on this.

Which makes me believe loading an arm32 kernel as an Portable Executable instead of grub's LoadImage() and StartImage() services may be a game-stopper. NOTE : I understand this is necessary for chain loading efi stubs for secure-boot. IMO this is not the pursued goal here.

So I finally got around to spending some time on this last week and
closed out the last of the issues I had so it's now working, albeit
with very minimal testing. We currently have images building for
Minimal/Server/Workstation and I've booted Minimal on a couple of
devices using U-Boot/UEFI/grub2/kernel without issues.

There's nightly builds of F33 and rawhide:
https://kojipkgs.fedoraproject.org/compose/branched/latest-Fedora-33/compose/Server/armhfp/images/
https://kojipkgs.fedoraproject.org/compose/branched/latest-Fedora-33/compose/Workstation/armhfp/images/
https://kojipkgs.fedoraproject.org/compose/branched/latest-Fedora-33/compose/Spins/armhfp/images/

The UEFI enabled images are the ones with the arch at the end rather
than in the middle, eg: Fedora-Minimal-33-20201010.n.0.armhfp.raw.xz
