[meta-xilinx] what are the current, canonical xilinx-related layers

[Robert P. J. Day]

  cleaning up some old layer directories, and ran across four separate
xilinx-related git clones:

  linux-xlnx
  meta-petalinux
  meta-xilinx
  u-boot-xlnx

i'm about to start browsing each dir to see what's in it, but if
someone could save me the time and identify the canonical
xilinx-related content these days, i would be most appreciative.
