We're adding IPv6 support to our eCos-based products. The basic IPv6
support in the "full-up" application code is working fine (at least
with static and link-local addressing). The next big question mark is
RedBoot.
I need to either add IPv6 support to RedBoot or make some basic
changes to the way our product works (specifically how the application
is updated in the field). Many years back Andrew Lunn stated that
IPv6 support in RedBoot was not possibleP

My question is why?
I realize it might be a fair amount of work to implement some sort of
IPv6 support in RedBoot, but I'm wondering what would make it "not
possible".

Adding IPv6 to RedBoot is not impossible, but it will require a
large amount of work, certainly requiring changes to all the existing
code as well as adding additional support. Andrew's "not possible"
was most likely an expression of how involved this might be.

Hee, this was such a long time ago. Maybe it was referring to the
original poster adding the FreeBSD stack to his configuration and
expecting RedBoot to use it.
You might be able to steal ideas and code from uIP. I forget what
license it uses.
Or, depending on what you actually need from the boot loader, it might
be possible to swap to uboot, which seems to have some patches
floating around for IPv6 support.

IPv6 isn't exactly taking off like a rocket. :)

Yes, the poster to which you were replying was clearly pretty lost. I
wondered if "not possible" was meant in the context of his approach.

We require TCP support, which is UBoot doesn't have. My guess was
that it would be easier to add IPv6 to RedBoot than TCP to UBoot, but
that might be wrong.
The other option is to change our firmware update process and our main
eCos app so that the firmware update can be done via the eCos app
that's using the full-up kernel with IPv6 support. I've got a fairly
good idea how much work is involved in that, and I'm starting to
suspect it would be easier than adding ipv6 support to RedBoot
(especially if DHCPv6 and router advertisement support are needed) or
adding TCP support to UBoot.
