The new amd64efi BSP supports: - multiboot2 boot format. Runs well with GRUB. - console based on either EFI simple text output or GOP-based framebuffer - clock based on EFI event/timer API - early console using either hard-wired PC-AT serial or just memory buffer - with EFI support disabled the BSP is more or less equivalent to amd64 BSP with multiboot2 support
