BFE Engineering 42fb386f60 docs: ASCII typography and style normalization across all repo text
Replace every em dash with real punctuation (rewrites, not hyphen swaps)
in docs, code comments, scripts, configs, and the port records; convert
en dashes, curly quotes, ellipsis glyphs, arrows, and section signs to
ASCII; drop machine-writing tell phrases from living docs. ADR titles
now use a colon. The M2 bring-up DTS model string carried an em dash
into the patch series and its record echoes; fixed at both, and the full
series re-verified to apply cleanly onto pristine 6.18.46. One comment
in freshness.h deliberately names the em dash glyph the UI renders as
the unknown mark; that is data, kept as prose naming it.

Verified: cargo tests (sim, config-lint, rs485-bridge), shellcheck,
both driver MC/DC harnesses, patches-apply.

Overnight kernel-enablement run: results (2026-08-24 night -> 08-25)

Goal: port/enable every remaining RV1106 hardware capability on the self-built Linux 6.18.46, open-source-first, verify on hardware, so the display's last mile can start in the morning. Runs on warden-c8a3 (_b slot = our 6.18).

Verified on hardware this run

Driver Evidence
AIC8800 wifi (M5) wlan0 up, iw scan found the site AP at -43 dBm + others. Modules (built-in deadlocks the two-stage SDIO bring-up).
TRNG /dev/hwrng, rng_current=rockchip-rng, real entropy.
OTP/nvmem rockchip-otp0 reads chip id ("MR1").
GMAC (wired eth) eth0: Link is Up - 100 Mbps/Full.
SARADC iio:device0 reads 2 channels (adc-keys).
Audio card rv1106-acodec, /dev/snd/pcmC0D0p+pcmC0D0c. Audible test -> bench.

(These join the earlier-verified set: clk, pinctrl, GIC, timer, DMA, eMMC, uartx3, i2c, wdt, RTC, tsadc, RGA, USB host, PWM backlight. VOP display binds: connector is the morning task.)

Cross-cutting fixes made this run

  • XZ compression (CONFIG_KERNEL_XZ): the growing kernel overran U-Boot's DTB-at-0xc00000 load boundary (Sysmem Error, FLARE-AB fell to _a). zImage 12.1->8.3 MB, ~4 MB headroom. See kernel-618-btest-cycle memory + wifi doc.
  • Module vs built-in: wifi must be modules (SDIO two-stage bring-up races the mmc probe when built-in: sequential initcall deadlock). Audio/GMAC/etc. are built-in and fine.
  • Hardened the c8a3 _b-test -> _a-recover cycle (compact-hex AVB serial write + readback while stable; Pi golden-env fallback for bootcount->loader).

Not done: deferred with reasons (see CAPABILITIES-AUDIT.md)

mailbox (binds via rk3368 fallback but no client to exercise), crypto-v3 (CPU crypto extensions already cover it; 100 KB port), NPU (no open userspace), pvtm (DVFS-only). Camera/ISP/SPI: no hardware. No unexplored capability gap.

Morning (needs a human at the bench)

  1. Display connector: VOP binds + DRM card0 + panel probes, but no connector link yet; needs eyes on the panel (pixels can't be verified over serial).
  2. Audible audio: speaker-test/aplay through the acodec.
  3. Wifi boot-time auto-load (modules currently insmod'd by hand): a loader that inserts aic8800_bsp->fdrv(->btlpm) from the rootfs.

Provenance: every ported driver is GPL-2.0 kernel source (PROVENANCE.md).
