Commit 393fccdf6c73 ("efi_loader: efi_guid_t must be 64-bit aligned")
has changed the alignment of efi_guid_t. This changed the size of
struct efi_configuration_table on 32-bit systems form 20 to 24 bytes. As
an array of this type is pointed to by the system table this breaks
compatibility with existing versions of GRUB and Linux. Let's get back the
original size by using the attribute __packed.

Similar to a "real" UEFI implementation, the bootmgr looks at the
BootOrder and BootXXXX variables to try to find an EFI payload to load

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
