This way debug commands which previously took only yes/no or on/off or enable/disable can take any of those options. BUG=chrome-os-partner:18467 BRANCH=none TEST=Try "on", "off", "yes", "no", "true", "false", "ena", "disable", for each of the following commands: - ilim (spring) - pll (link) - power (spring/snow) - hcdebug (all) - kblog (link) - ksscan (all) - lp5562 (spring) Change-Id: Ie8e0fae3775b1da711864bcba6682ba5e68a06f1 Signed-off-by: Randall Spangler <rspangler@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/46900 Reviewed-by: Bill Richardson <wfrichar@chromium.org>
