Awesome, thanks for doing this and it was good to have
some face2face time at ELCE.

I've merged this into my personal sunxi-wip u-boot branch,
I've made 2 changes:

1) in : ?sunxi: DRAM initialisation for sun9i" there are a
lot of #if 0 #endif blocks, most of these document some features
which we may want to enable in the future, but a few were just
dead weight IMHO, so I've pruned a few

2) in : "sunxi: Add support for A80 Optimus board", we already
have a configs/Merrii_A80_Optimus_defconfig, so I've made the patch
update that instead of adding a new defconfig

I have not tested this yet, I will do tomorrow, assuming it
works for me too I will include it in my next pull-req (*) and
try to get it included in the 2016.11 release, yes the merge
window has closed, but the changes here are very isolated so
I will try and see what Tom says :)

Regards,

Hans


*) Which I hope to send out this weekend
