Background: with a normal UEFI implementation, the boot process is: a) firmware (u-boot) looks at BootOrder and the BootXXXX variables to try to determine what to boot. b) the firmware will look at the BootXXXX variables (which contain an EFI_LOAD_OPTION "struct" in order specified by BootOrder, and will boot the first bootable option. c) The EFI_LOAD_OPTION specifies a device-path which identifies the device and file path of the .efi payload to exectute. This is implemented with the 'bootefi bootmgr' command. If there are no bootable options the firmware falls back to loading \EFI\BOOT\bootaa64.efi (exact name varies depending on arch), which for distro's using fallback/shim (which should include most modern linux distros) then loads fallback.efi which uses the EFI_SIMPLE_FILE_SYSTEM_PROTCOL and EFI_FILE_PROTOCOL to search for any \EFI\*\boot.csv, and will then set BootOrder and BootXXXX EFI variables accordingly so that on next boot fallback.efi is not necessary. The last 5 patches are a bit unrelated, just pulling forward some of the patches I have from the next patchset, to get Shell.efi and SCT working.
