From 9975fe96b697b6d64bde3f77cd08612fec812b47 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 13 Sep 2017 18:05:38 -0400 Subject: efi_loader: add bootmgr Similar to a "real" UEFI implementation, the bootmgr looks at the BootOrder and BootXXXX variables to try to find an EFI payload to load and boot. This is added as a sub-command of bootefi. The idea is that the distro bootcmd would first try loading a payload via the bootmgr, and then if that fails (ie. first boot or corrupted EFI variables) it would fallback to loading bootaa64.efi. (Which would then load fallback.efi which would look for \EFI\*\boot.csv and populate BootOrder and BootXXXX based on what it found.)
