Full .dts + fixed 7.2 kernel still resets in <2s with no output. Cut the .dts to SoC + regulators + debug UART + HS-peripheral USB only - no reserved-memory, no simple-framebuffer, no touch/SD/UFS/keys. If this reaches the initramfs the fault was in a removed node; if it also resets the problem is the kernel/config/boot image.
