Translations:NixOS on ARM/UEFI/15/en

Other than letter salads, they are Server Base Boot Requirements and Embedded Base Boot Requirements. Two specifications for ARM. If your target is in compliance with either, booting with UEFI should already be supported. With the minimal UEFI support in U-Boot, targets that were not made to be EBBR compliant can be made compliant, or be close enough for what it matters.
