The recent addition of the multicomponent version string for cr50, requires further tweaking of the version generating script. In particular, the CROS_EC_VERSION32 variable used by the "verson" cli command is not supposed to include any information about subcomponents of the image, it should reflect the EC version only. Separating everything after the first space accomplishes that. BRANCH=none BUG=chrome-os-partner:55373 TEST=verified that RO_x and RW_x versions are printed properly: > vers Chip: g cr50 B2 Board: 0 RO_A: 0.0.1/84e2dde7 RO_B: * 0.0.3/8fe06b9e RW_A: cr50_v1.1.4992-7c9f891+ private RW_B: * cr50_v1.1.4989-52b3cc6+ ...
