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). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017wB8KB3MMQztRDXCMCkPrf

This is support for the AIC wireless chip (AIC8800DC SDIO combo
|
|
wifi+BT on the WardenOS 86-Panel). Build as a module (m); built-in

deadlocks the two-stage SDIO bring-up (see note above).
