If you look at the patch adding support for the i2c controller I needed
to make some changes to the link script, I probably forgot to make the
same changes to the fel link script...

True, feel free to amend the commit msg, or let me know if you want a v3.

And thanks for looking into merging this into sunxi -next. I was planning to
drop you a mail about coordinating getting this added vs getting your ahci
patches added. I assume you ahci patches are good to go too, or ... ?

Next I want to start adding support for more boards. For starters I would
like to add all boards which also have a dts file in the upstream kernel.
Ideally I would start working on that once you're done with adding this
series + your ahci patches so that we don't get in each others way. Can you
send me a mail when you're done (for a while at least) then I'll try to
get a set of patches for this to the list based on top of your latest work.

Except for sun4i-a10-hackberry.dts and sun4i-a10-inet97fv2.dts I've hardware
to test on for all sun4i, sun5i and sun7i models which have a dts file, not
sure what to do with the 2 I cannot test.

Hans
