Marrying U-Boot, uEFI and grub2
Talkat Embedded Linux Conference + OpenIoT Summit North America 2017 · on Thursday, 2017-02-23· at 15:30· Broadway III/IV·
summary
Demonstrates a working stack that layers grub2 atop UEFI atop u-boot so a single distro image boots ARM boards: u-boot loads an efi_loader that exposes UEFI objects, grub2 as an EFI payload boots the Linux EFI kernel, and Raspberry Pi 3 boots in QEMU; ISO/El Torito-as-partition and DHCP/TFTP network boot are implemented upstream. Runtime UEFI services and secure-boot are not yet complete; code impact is tiny — about 10 KB overhead — and the flow supports unified device trees and removable media fallback.
