BFE EngineeringandClaude Fable 5 3d3b35459e 6.18 boot-splash chain: seamless VOP takeover, drm-logo reservation, gzip kernel, chosen-bootargs dedup
Kernel-side captures for the flare-edge warden-bootimprovements work,
photon-verified on warden-c8a3:

- rockchip_drm_vop.c vop_initial(): when U-Boot left the VOP scanning the
  boot logo (window enabled, not in standby), skip the AHB/dclk resets and
  window disables, and hold clocks + a runtime-PM reference until the first
  real vop_enable() drops them. The logo now survives the DRM bind; the
  only remaining blank is ~1.3s at the splash's own first modeset.
  KNOWN LOOSE END: a deferred-probe rebind runs the takeover twice and the
  first bind's held references are never dropped (a clk/PM leak that keeps
  the VOP domain on -- harmless for an always-on HMI, should be released in
  unbind eventually).
- rv1106-warden.dts: /reserved-memory/drm-logo@0 placeholder that U-Boot's
  fdt fixup stamps with the logo framebuffer (observed: addr=0xdf00000
  size=0x71000, kernel reserves it 'map non-reusable'); chosen bootargs
  drop earlyprintk (with earlycon it doubled every console line at 115200).
- Kernel config switched KERNEL_XZ -> KERNEL_GZIP: post-'Starting kernel'
  silence 4.2s -> 0.8s; the zImage grows past the old 11.95MB cap, which
  flare-edge sdk-patches 0007 removes (fdt_addr_r 12M -> 128M).
