M1 is complete (clk + pinctrl + mach compile clean); this reaches M2's build milestone. multi_v7_defconfig + configs/m2-earlycon.fragment builds an 11.8 MB zImage with clk-rv1106.o and pinctrl-rockchip.o (our rv1106 data) compiled into the full tree — no rv1106 warnings. dts/rv1106-warden-m2.dts (CPU, GIC-400, arch timer, 256 MiB RAM, GRF, the CRU, uart2 as snps,dw-apb-uart) compiles clean at W=1 with earlycon=uart8250,mmio32,0xff4c0000. Reproducible via build-m2.sh. Boot is the next step and is on-hardware/attended: package zImage + dtb, load on a bench unit with a recovery net, watch for the earlycon "it's alive". PORT-VERIFY before trusting a boot: DDR size/base, the CPU clock mux, console baud.
