True. But the work I mentioned is happening is to move this to 3.4.
3.2 is the version that Xilinx requested for initial integration as a
yocto BSP, so that's where it sits for now.

Niether do I.

In this case, they were hoping to track the yocto kernel versions to
not make version skew or spread the version landscape anymore. As far
as I know, this is still the case, since it makes the route to commercial
support simpler in some cases.

I'm sure we can work through them, I'm raising the right people at
Xilinx to discuss as well, since in the end, their voice carries the
most weight.
