This change moves vendor specific temperature ranges to battery pack files or board setup files. And added a host test case to verify that does not change x86 smart battery charging state machine behavior. BUG=chrome-os-partner:21181 BRANCH=None TEST=manual build test: util/ecmakeall.sh hosttests: make hosttests && make runtests Change-Id: I48e76826b5555f64b78e3c063ce5f02416c72aa2 Signed-off-by: Rong Chang <rongchang@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/62978 Reviewed-by: Vic Yang <victoryang@chromium.org>
