BFE EngineeringandClaude Opus 4.8 92905bf4d4 kernel/rv1106: M5 wifi VERIFIED on c8a3 — wlan0 scan works (module build)
On-hardware proof (self-built 6.18.46, _b slot): aic8800 modules load,
download firmware, wlan0 up ([device-mac]), iw scan finds real APs
incl. SSID BlueFlare @ -43dBm. RF path fully functional. See
wifi/VERIFIED-on-c8a3.md.

Two changes from the initial built-in attempt:
- Built-in =y DEADLOCKS: aicbsp_init's eager SDIO bring-up (device_initcall,
  sequential) blocks the dw_mmc controller probe that would enumerate the
  card it waits for (aicsdio.c:597 2s down_timeout -> unregister). Converted
  to modules (=m): AIC_WLAN_SUPPORT bool->tristate; loaded late, after the
  mmc-pwrseq enumerates the card — the vendor-proven flow.
- Restored fdrv's own md5.o (each .ko needs its own MD5; bsp doesn't export
  it). Refreshed kbuild snapshot accordingly.

Kernel-size fix (CONFIG_KERNEL_GZIP -> XZ): the wifi kernel's 12.12MB gzip
zImage overran U-Boot's DTB-at-0xc00000 load boundary (Sysmem Error, FLARE-AB
fell back to _a). XZ -> 8.15MB, ~4MB headroom; also correct for a firmware
kernel. Uncompressed Image ~30MB but the ARM decompressor relocates the FDT
at runtime, so only the U-Boot load-time overlap mattered.

DRIVER-PARITY: wifi  M5; BT 🔨 (module built, HCI not yet exercised).

BFE EngineeringandClaude Opus 4.8 6897c9f93e 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.
