Per [maintainer]: forward-port the RV1106 SoC enablement from the vendor 5.10 tree to
6.18 LTS ourselves (no plan44), on our Buildroot. Verified mainline has ZERO
RV1106 support, so this is a whole-BSP port. docs/bringup.md = the console-first
milestone plan + method (sibling-delta from rv1126/rv1108, which exist in both
trees). M1 (clk driver) underway: gcc-8.3 builds 6.18; wired CLK_RV1106; ported
55 CRU macros + the panic_notifier header split + the armclk signature change
(flagged PORT-VERIFY for the CPU-mux, TRM-check needed). Captured in
rv1106-enablement/. Honest: first of ~120 files; multi-month effort.

Grounded in a full survey of the flare-edge firmware: catalogs every hardware
seam (register/MemBus, resource-path env-override, RGA compile-time), the tiered
MC/DC target (our code real MC/DC via the uboot-ab pattern; blobs fault-injection),
the target-config-lint class that the sim CANNOT cover (the 0x40000 brick), and
the ordered plan. Notes the flared<-warden-sim Cargo dep needs a repo remote
([maintainer] go-ahead).

New from-scratch SDK for WardenOS (RV1106). First substance: the hardware
simulator's core — a MemBus register/SRAM seam (one trait, real /dev/mem backend
on device + in-memory SimBus on host) and a faithful port of the HPMCU watchdog
firmware (hpmcu/watchdog/main.c) as HpmcuSim, with 8 tests validating boot-grace
fire, heartbeat-timeout, disarm stand-down, and the flared arm-within-grace safety
property (no boot-loop) — all off-device, in a virtual clock, in <1ms.
This closes the gap the Explore map flagged: flared's devmem.rs/hpmcu.rs are the
only register-touching modules with zero tests. README lays out the SDK vision
(modern kernel, tiered driver MC/DC, proper RGA/HPMCU/NPU simulator, own repo).
