Fragment vs Fragement

I’m troubleshooting a device-tree and have come across the keywords “fragment” and “frag e ment” in my decompiled blob. At first, I thought it was a typo, but I see the same thing in dtb file provided by NVIDIA in the Linux for Tegra source code(4.9.140).

I can’t find any information on what a fragement is and how/if it differs from a fragment.
