I don't like the idea of distribution specific stuff getting into U-Boot. We would end up with a plethora of possible UEFI binaries to search for: shim, GRUB, iPXE, any Linux kernel. All of these are binaries could be used for booting Fedora, Debian, or any other Linux distribution via bootefi. And which one should we take if there is more than one of these? I especially dislike any claim that one distribution is "major" and another is not. Should we kick out CentOS and Fedora because they are less popular than Ubuntu and Android? So let's leave it to the distribution to create boot.scr or provide a binary following the naming convention given in the UEFI specification (chapter 3.5.1.1 Removable Media Boot Behavior). > >> >> # Booting via boot script. >> >> On Debian I use package flash-kernel to keep /boot/dtb in sync with the >> kernel and have a u-boot.scr.uimg script with something like the >> following lines: >> >> setenv bootargs console=${console} >> load mmc 2:1 ${kernel_addr_r} EFI/debian/grubarm.efi >> load mmc 2:2 ${fdt_addr_r} dtb >> bootefi ${kernel_addr_r} ${fdt_addr_r} > > > flash-kernel is interesting.

I have separate partitions: /boot of type 83 (Linux, ext2) and marked as bootable and with boot.scr on it. /boot/efi of type ef (EFI, vfat) and not marked as bootable The sequence on the block device does not matter. When booting via iSCSI with iPXE I put boot.scr and snp.efi on an EFI partition marked as bootable.

We'll either support runtime variables as defined in the UEFI spec or present a cached copy on Linux. You can then build a capsule and update the variables on next boot. In any case capsule updates are not supported yet, so any path we choose requires some development. I'll try to keep both of you updated on the development process. Cheers /Ilias

Thanks, Michal If you boot the kernel of the Debian installer via UEFI, it installs GRUB EFI but you may have to install flash-kernel manually. If you you want to use iPXE on ARM, you are on your own. There isn't even a package with snp.efi provided by Debian. But at least the installer allows you to set up your partitions and do the installation on an iSCSI drive. Best regards Heinrich

Thanks, Michal # Booting via boot manager U-Boot currently has no runtime support for variables. But Linaro is working on it. So update-grub cannot set the variables for you. You can use the efidebug command to prepare for booting via the boot manager: => efidebug boot add 0001 Debian mmc 0:1 \ efi/debian/grubarm.efi console=${console} There seems to be a bug with communication lines in U-Boot.
