[meta-xilinx] xilinx 4.4 -> 4.6 kernel doesn't boot

[Arno Steffens]

I found the issue in the devicetree, comparing my one with recent microzed board.
Nevertheless there is (at least) one thing, I don't understand.

in meta-xilinx/recipes-bsp/device-tree/files/common
there is zynq7-base.dtsi, which is not uses by all the devicetree files in this layer.

These are all using:
/include/ "zynq-7000.dtsi" - but this is not in .../common

Is this intentionally?

And it seems the number of Bogomips is only half of previous values (even after adding 2nd CPU)?

Regards
Arno
