On the board I have, the M3 image goes into its own reserved region with board data between the two. Patch 1 lets IPQ8074 name its regions "q6" and "m3" and give a second firmware name; patch 2 loads M3 into that region before the authenticated Q6 image. Without memory-region-names nothing changes for any compatible. Testing: - dt_binding_check (dtschema 2026.9) passes; the schema also rejects named regions on other compatibles and a named IPQ8074 node with only one region or one firmware name. - arm64 W=1 build of the driver as a module, no warnings. - Not booted in this form. The equivalent change on OpenWrt's earlier copy of this driver has run on every boot of a Netgear RAX120 v1 (IPQ8074 hw1.0, WLAN.HK.2.0-01792-QCAHKSWPL_SILICONZ-1). Varadarajan, would you rather fold this into your series, or should I resend it once v14 is merged? I am happy to test either way on that board. This work was developed with AI assistance (Assisted-by tags on each patch).
