kernel/rv1106: M5 AIC8800 wifi/BT port — build-verified, capture recipe
Driver built into self-built 6.18 (=y): zImage 12.7MB + rv1106-warden.dtb build clean; System.map confirms aicbsp_sdio_driver, aicwf_sdio_driver, rwnx_cfg80211_ops linked with correct bsp->fdrv->btlpm initcall order (host nm/System.map — cross-nm/ar mis-list these, verify with System.map). Recipe captured (driver .c is vendor GPL source in the SDK, not duplicated): - kbuild/ — from-scratch in-tree Kconfig + Makefiles (bsp->fdrv->btlpm link order; tristate->default y; AIC_FW_PATH as a real Kconfig string symbol). - wifi-dt-block.dtsi — sdio_pwrseq (mmc-pwrseq-simple, reset gpio1 PA2) + &sdmmc (mmc@ffaa0000, supports-sdio, cap-sdio-irq, non-removable). - PORT-PROGRESS.md — full file->change log: ~30 timer/netdev renames, 7 cfg80211_ops signature deltas, link_id args, wakeup_source API rewrite, 49 bsp/fdrv symbol collisions renamed aicbsp_priv_*, rwnx_mesh restore. Firmware present on both oem_a+oem_b (/oem/usr/ko/aic8800dc_fw); on-hardware wlan0 verify next.
