Build RDK Linux kernel, device-tree, and driver-module artifacts with mk_kernel.sh (X5 also offers mk_kernel_rt.sh). Require board family, target, config source, and deployment target; confirm boot replacement or reboot. Use for kernel/DTB/module/RT work, not full images (bsp-image-build), deb packaging (bsp-deb-build), or S-series (bsp-s-series).
