Hi David,

This issue might be related to the fact that the device tree in the
meta-xilinx layer for the microzed has a compatible string listed for
the phy node. The mainline kernel hasn't got that
(https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/zynq-microzed.dts?id=refs/tags/v4.10-rc5#n52).

Could you try removing the compatible string set. Also please provide
the full kernel boot log if possible.

Not sure what you are referring to here, you will need to provide more
details. The DMA drivers in the kernel have changed over the past few
releases (they have been upstreamed), and some of the dts bindings
have changed too. Kernel log and error messages would be useful here
too.

Nathan
