[meta-xilinx] Devicetrees and kernel version

[Elvis Dowson]

Hi Philip,

I would think that any dts files that go into conf/machine/board,
should be generic enough to work across multiple IP cores
revisions, by setting it to the lowest compatible IP core revision
number.

I think if that you start adding conf/machine/board/linux-xlnx_3.13
it would start messing up the norm, i.e. kernel version specific files
normally reside in the kernel recipe folder.

Another point to reflect upon, in terms of alternatives, is if we had
adopted the linux yocto LTSI approach, each per kernel git repo
could maintain its own device tree file.

Regards,

Elvis Dowson
