# These variables should reflect the linux-xlnx SRCREV and Linux version of
# latest upstream linux release merge. If these are out of date, please email 
# meta-xilinx@yoctoproject.org to have it corrected. The linux-xlnx-dev build 
# should still function correctly with out of date values, but the naming will 
# be missleading.

# LINUX_VERSION is set to select the defconfig and dts we wish to use within
# meta-xilinx. If the build fails it may be because this defconfig is out 
# of date. If that happens or if the developer desires a non meta-xilinx config 
# they should add the defconfig and name it appropriately so the recipes find
