Reclaim DRAM by disabling unused subsystems across MB1 BCT, MB2 BCT, kernel reserved-memory, and SWIOTLB. Use for headless or no-camera Jetson deployments; not for CPU/GPU frequency tuning.

When to use

• Cut the unused DRAM carveouts that ship enabled in the reference BSP when a Jetson deployment skips display, camera, or other peripherals, freeing the freed bytes for the application. Always edits the four layers in boot order so an early-…

When not to use

• Only the validated recipes (`headless`, `no-camera`, `swiotlb`) are
• SWIOTLB shrink is bounded by peak in-flight DMA — exceeding the new
• BPMP-DTB edits land in the overlay tracker only after Customize +
