confirmed by u-boot output = below:

For the marvell,mv78230-a0-i2c = unfortunately i've spend 3 hours
trying to understand this but it = only works with this on the
ix4-300d :(. There was multiple patch = around this and maybe one
broke the auto-detect part of this, I've = tried compiling with some
3.10 or lower kernel but no luck here I = still have to put this a0
option.

Lets first = confirm you have an a0 SoC.

At boot time, it should = print:

pr_info("MVEBU SoC ID=3D0x%X, Rev=3D0x%X\n", soc_dev_id, = soc_rev);

What revision do you have?

If the auto detect = code really is broken, Gregory will likely take a
look.
