Actually, the default environment present in the barebox mainline for
the cfa10036 is looking for a kernel named zImage-cfa10036 and DTBs
named oftree-${DTB_BOARD_NAME} in /boot. So I'm just creating more links
to the kernel and DTBs. I'm not doing anything differently, I'm just
creating more links.
