Variable efi_system_partition holds the efi_system_partition. Currently it is initialized as:
{ .uclass_id = 0 = UCLASS_ROOT, .denum = 0, .part = 0, }
This indicates that host 0:0 is the efi_system_partition and we see output like:
=> bootefi hello ** Bad device specification host 0 ** Couldn't find partition host 0:0
To identify that no EFI system partition has been set use UCLASS_INVALID.
