Removing that solves the problem, thanks. But what surprise me is that
these problems starts with the commit that I mentioned before
(061a16fd21bc0f419eda03aee6ee0ce11b48f27) which seems that only changes
some kernel configuration and anything more. Doing a checkout to the
previous commit don't have these problems.
I don't know why but seems that setting CONFIG_FIXED_PHY to something
different from "y" fixes the problems too. Also, I found that my board
uses Marvell 88E1510 not the 88e1512, so appending the right compatible
string also fixes it (then I don't understand how this problem don't
have occurred before). Anyway, the compatible string for the
ethernet-phy (in the microzed dts) is not missing the 88e1510?
I suppose that the problem about the DMA is some configuration option
that should be enabled/disabled I will try to see what have have changed
and configure it properly. I attach the full log after fixing the
Ethernet problem.
Thank you very much for your time and sorry for my ignorance.
