Update lm3s3748 support: split EK board support out from the target CPU support ... other boards with this chip will likely be set up differently.
Shrink some too-long lines in that target CPU support. --- tcl/board/ek-lm3s3748.cfg | 17 +++++++++++++++++ tcl/target/lm3s3748.cfg | 35 +++++++++++------------------------ 2 files changed, 28 insertions(+), 24 deletions(-)
