ScottW514 11fec891ed ffboot v2: slot inventory, verified atomic env flips, target probe
-l inventories every bootable partition (SD, eMMC slots 1/2, legacy
p4) as machine-parsable key=value lines: firmware type
(forgefirm/factory), version, kernel presence, booted/next markers,
plus the saved-env selection - the shared probe for the installer and
the forgectrl update manager.

Boot switching now writes all four selection variables (mmcdev,
mmchwpart, mmcpart, mmcroot) in one fw_setenv -s transaction and
read-back verifies, falling back from the libubootenv script format
to the classic u-boot-tools format to per-variable writes - the same
script works on factory firmware and ForgeFIRM. mmchwpart was
previously never set and a mixed env could survive a mid-flip power
cut. Switch targets must pass a content probe (rootfs mounts, kernel
present) unless -f. -e picks the newest factory slot by probing,
excluding slots occupied by ForgeFIRM.

The new ffboot recipe installs it as /usr/sbin/ffboot with
/etc/fw_env.config (factory-identical redundant env layout at eMMC
0x80000/0x82000) - previously the image shipped fw_setenv with no
config. Added to forgefirm-image.

DESCRIPTION = "OpenGlow/ForgeFIRM image for Glowforge"
# ForgeFIRM cuts the cloud dependency: drop the Glowforge cloud client
# (gfui-client connects to Glowforge's servers). Removing it here (override
# only; the shared glowforge-image base is untouched) also sidesteps its
# do_package failure. Its slot is filled locally by forgectrl (camera MJPEG
# service; the grblHAL controller recipe is tracked in kas/README.md
# backlog #5).
IMAGE_INSTALL:remove = "gfui-client"
# grblhal-glowforge: the grblHAL motion controller (Grbl over TCP:23).
# forgectrl: the ForgeFIRM control daemon (camera MJPEG service on :8080).
# gfhome: one-shot Glowforge web-service homing, invoked by the controller
# for $H when homing_mode = gfcloud (/data/forgefirm.conf).
# v4l-utils provides media-ctl / v4l2-ctl for the imx-media pipeline (also a
# forgectrl runtime dependency, kept explicit here for bring-up use).
# fwup: applies signed .fw archives (ForgeFIRM upgrades + factory restore)
# to the inactive rootfs slot.
# ffboot: boot-slot inventory and switching (also ships fw_env.config).
IMAGE_INSTALL:append = " grblhal-glowforge forgectrl gfhome v4l-utils fwup ffboot"
# The release rootfs must fit a 200 MiB factory eMMC slot (409600 blocks).
# Sizing: content + 40 MiB working space, hard-capped at the slot size —
# the build fails rather than emit an unflashable image. The raw ext4 is
# deployed alongside the wic; scripts/mkfw.sh packs it into the signed
# .fw release artifact.
