We often find it handy to build test images that are unlocked or have special powers. To avoid confusing these with production images, this adds a "DEV/" to the version string: "make BOARD=cr50" looks like this: > version Chip: g cr50 B2 Board: 0 RO_A: * 0.0.9/0088a3eb RO_B: 0.0.8/710d4375 RW_A: * 0.0.6/cr50_v1.1.5261-4848d7e RW_B: 0.0.6/cr50_v1.1.5261-4848d7e [...] "CR50_DEV=1 make BOARD=cr50" looks like this: > version Chip: g cr50 B2 Board: 0 RO_A: * 0.0.9/0088a3eb RO_B: 0.0.8/710d4375 RW_A: 0.0.6/cr50_v1.1.5261-4848d7e RW_B: * 0.0.6/DEV/cr50_v1.1.5261-4848d7e [...] BUG=chrome-os-partner:55557 BRANCH=none TEST=make buildall; also.. Build both with and without the CR50_DEV=1 environment variable. Observe that the version string differs even if nothing else does.
