This patch set is a collection of patches to enhance efi user interfaces /commands. It will help improve user experience on efi boot and make it more usable *without* edk2's shell utility. Let's see how it works: => efitool boot add 1 SHELL mmc 0:1 /Shell.efi "" => efitool boot add 2 HELLO mmc 0:1 /hello.efi "" => efitool boot dump Boot0001: attributes: A-- (0x00000001) label: SHELL file_path: /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/SD(0)/SD(0)/HD(1,MBR,0x086246ba,0x800,0x40000)/\\Shell.efi data: Boot0002: attributes: A-- (0x00000001) label: HELLO file_path: /VenHw(e61d73b9-a384-4acc-aeab-82e828f3628b)/SD(0)/SD(0)/HD(1,MBR,0x086246ba,0x800,0x40000)/\\hello.efi data: => efitool boot order 1 2 => efitool boot order 1: Boot0001: SHELL 2: Boot0002: HELLO => run -e Boot0002 (or bootefi bootmgr - 2) ; '-' means no dtb specified WARNING: booting without device tree Booting: HELLO ## Starting EFI application at 000000007db8b040 ...
