CTF: UEFI HTTP boot support

[Miguel C]

I don't think it needs the cdrom driver does it? UEF accepts a iso (since
2.5) has a http boot URI and that is mounted as a ramdisk via the http boot
driver itself (I think, this is all a bit new to me too :)


Most of the info I found on it is from tiano core:

I did just find the presentation/demo of this working with the FreeBSD
amd64 iso that I bumped into before:
