(define-public grub-efi-bootloader-chain-raspi-64
;; A bootloader capable to boot a Raspberry Pi over network via TFTP or from
;; a local storage like a micro SD card. It neither installs firmware nor
;; device-tree files for the Raspberry Pi. It just assumes them to be
;; existing in boot/efi in the same way that some UEFI firmware with ACPI
;; data is usually assumed to be existing on PCs. It creates firmware
;; configuration files and a bootloader-chain with U-Boot to provide an EFI
;; API for the final GRUB bootloader. It also serves as a blue-print to
;; create an a custom bootloader-chain with firmware and device-tree
;; packages or files.
