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.
Adding the eMMC dw_mmc node (mmc@ffa90000, clocks from cru + grf_cru) was all M3
needed. On warden-c8a3 the 6.18 kernel enumerates the eMMC at HS200
(mmcblk0 8GTF4R 7.28 GiB), mounts the ext4 rootfs, runs /sbin/init, and starts
every WardenOS daemon. Serial root login confirms:
Linux warden-c8a3 6.18.46 armv7l
ps: warden-flared warden-modbus warden-mikrotik warden-asic warden-ui warden-flight
Expected M4/M5 gaps are clean failures: the 5.10 aic8800 wifi/BT .ko won't load on
6.18 (vermagic), and no backlight/framebuffer yet (no VOP node). Next: M4 display,
M5 AIC8800 SDIO port, M6 the rest; plus a lean defconfig + Buildroot-on-6.18.

The Linux 6.18.46 forward-port boots on the panel through our ported drivers,
verified on the serial console: earlycon, arch timer (BogoMIPS calibrated), our
clk-rv1106 CRU, pinctrl, and the mainline 8250 bound to uart2 clocked by our CRU
(ttyS2 16550A), then rootfs mount.
Two DT fixes got it past "Starting kernel":
- fdt placed high (load=0x08000000) so the bloated multi_v7 zImage (~20 MiB
decompressed) stops overrunning the DTB at 0xc00000 (was: r2=0, "invalid dtb").
- added the rockchip,rv1106-grf-cru node (grf-clock-controller child of grf) so
clk-rv1106's grf_ctx isn't NULL (was: panic in rockchip_clk_register_branches).
Console pinned to 115200 (readable on the CP2102 bench adapter; prod uses 1.5M).
The boot-image format and the A/B _b-slot safe-test method (which auto-reverted to
_a on every failed attempt) are in docs/m2-boot-on-c8a3.md. M3 next: lean defconfig
+ dw_mmc DT + our Buildroot userspace rebuilt on 6.18.

M1 is complete (clk + pinctrl + mach compile clean); this reaches M2's build
milestone. multi_v7_defconfig + configs/m2-earlycon.fragment builds an 11.8 MB
zImage with clk-rv1106.o and pinctrl-rockchip.o (our rv1106 data) compiled into
the full tree — no rv1106 warnings. dts/rv1106-warden-m2.dts (CPU, GIC-400, arch
timer, 256 MiB RAM, GRF, the CRU, uart2 as snps,dw-apb-uart) compiles clean at
W=1 with earlycon=uart8250,mmio32,0xff4c0000. Reproducible via build-m2.sh.
Boot is the next step and is on-hardware/attended: package zImage + dtb, load on
a bench unit with a recovery net, watch for the earlycon "it's alive". PORT-VERIFY
before trusting a boot: DDR size/base, the CPU clock mux, console baud.
