Thank you too. I'm really happy to see this getting into u-boot proper.
Beginner question, since this does not touch existing code, will it
still go into the 2014.07 release ?

I've been working on a patch-series for adding sun4i and sun5i support,
which has been almost done for 2 weeks now, seeing Ian's part of this
effort merged surely motivates me to finish that work quickly :)

sun6i (aka A31) support unfortunately is a different story, once I've
the sun4i / sun5i support series finished, I can relatively easy
also give you a 2nd series adding the sun6i support which we have
in the u-boot-sunxi git repository (the need for which will hopefully
go away completely soon). But this support is incomplete, it needs
allwinners boot0 and boot1 binaries to boot-strap u-boot, since we
don't have dram setup code yet. With these binaries you should be
able to be able to ie boot a Linux kernel with this u-boot, but
it is not a standalone solution. Let me know if you're interested in
receiving a series with this (incomplete) support.

I've given a friend of mine an mele A1000G quad to work on the dram
setup code, I'll ping him on this.

Hans
