URL: https://svnweb.freebsd.org/changeset/base/323063
Log:
boot1.efi: print more info about where boot1.efi is loaded from
Print the device that boot1.efi was loaded from. Print the path as
well (since it isn't included in DeviceHandle). Move block where we do
this earlier so all the block handle code is now together.
