0ba8d3fbae efi: added refind to the rescue
Its bootloader autodetection capabilities can prove quite useful;
this particular addition has been "sponsored" by this thread:

36a707bbb2 efi: refind support
mkimage > 0.2.5 should have received enhanced UEFI support
including the ability to setup refind (#28349);
make the feature ready for that.

8c8d7c24d1 efi: initial signed bootloader support
The implementation goes the shim[1] way as described here[2];
many thanks to Matthew Garrett and Rod Smith.

cd0db8d363 efi: handle rescue as well
The rescue feature intentionally doesn't pick up THE_PACKAGES
and THE_LISTS into stage2, so add EFI ones explicitly.

b6eb7cb732 efi: skip on unsupported target architectures
There's a possibility to run into IA32 EFI but that's rather
uninteresting hardware (ancient Xeon servers and <s>outdated</s>
early Intel Mac laptops).  Just drop it on the floor.

As x86_64 UEFI support would result in "2D hybrid(r)(tm)" image
which boots with all combinations of BIOS/UEFI by CD|DVD/Flash
(or at least should boot), some downgrace seems due: use/efi will
turn use/isohybrid on non-x86_64 -- which will require further
tweaks on PPC/ARM some day.

5a61e2d4cc efi: employ mkimage
The initial approach required some quite involved postprocessing
as described in http://www.altlinux.org/UEFI#HOWTO; after having
ironed out the kinks so that initial EFI support could be merged
into mkimage proper we're better off just using it, eh?

653b8e1df8 initial EFI support
EFI/UEFI is mostly about partitioning and bootloader setup,
at least from a distribution's point of view; so the
appropriate tools should be handy and firmware interface
module should not be exterminated from installer images
but get autoloaded instead.

Please note that while there exists 32-bit x86 EFI
we don't bother with it at the time being: it's relevant
to some irrelevant Xeon systems as well as for the older
Intel Macs (<2008) that are long out of fashion anyways.
That is, initially we deal with x86_64 EFI only.
