This series adds basic IPv6 support to U-boot. It is a reboot of my earlier work on this[1]. Technically this is v4 of the series but with the amount of time that has passed, rebasing and running though checkpatch as well as the support for TFTP I've decided to reset the counter back to 1.
Most of this is ported from Allied Telesis' additions to u-boot[2]. (Note that I am employed by Allied Telesis[3]). The hard work was done some time ago by Angga, I've cleaned it up and made some improvements with the hope of getting it accepted upstream.
A few open issues/questions
1) Presumably the majority of the actual V6 code would be included by a config option. How far should I take that? Should the vsprintf code be conditional? I'm also not sure where to draw the line between CONFIG_NET6 and CONFIG_CMD_NET6, CONFIG_NET and CONFIG_CMD_NET look similarly confused.
2) This code parallels net.c and net.h. Should I continue this for the final version or integrate it into net.[ch].
3) rxhand_f currently takes an struct in_addr *. TFTP doesn't use this (I haven't looked at other users). To support V6 this may need to be a new union, a void * with some kind of flag or nothing if no rxhandler actually cares.

Since I'm subscribed to the list using my gmail account I've signed using that.
