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.)
