In fact, I got Linux kernel booting via bootefi command last week. I have tried to use as much as ARM stub code possible which will help in unifying them in future. I am yet to add UEFI run time services. But I was thinking to post a RFC series with EFI stub code first and work on run time services after that. Let me know if you think that’s not a good idea. > Thanks, > > Alex > > _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
