This adds the URI device path option for 'boot add' subcommand.
User can add the URI load option for downloading ISO image file

It might be a matter of personal preference, but
since the current syntax of efidebug is already much complex,
I don't want to add more options unless it's necessary.
How about re-using "-B" option, say
=> efidebug -B 3 debian-netinst uri - https://foo.com/baa
You just replace one set of alternatives (-B -b -u) against another
(mmc, nvme, uri, ...). I cannot see that this reduces complexity.
I understand your concern. OK, I will add uri in -b|B and also update
documentation.
It is unclear to me what the difference between -b and -B shall be for
URIs. Would -B be with the device path of the network device
(/VenHw()/MAC()/URI()) and -b without (/URI())?
Best regards
Heinrich
Thanks,
Masahisa Kojima
BTW, I think that <bootid> and <label> should have been moved out of "-b|B"
when Ilias introduced this new syntax.
