+One-line Summary: Update for namelists for spin-up
+Github PR URL: https://github.com/ESCOMP/CAM/pull/1517
+
+Purpose of changes (include the issue number and title text for each relevant GitHub issue):
+  - Namelist out of the box for the spinup:  https://github.com/ESCOMP/CAM/issues/1515
+
+Describe any changes made to build system: N/A
+
+Describe any changes made to the namelist: modified namelist settings as specified in #1515
+
+List any changes to the defaults for the boundary datasets: N/A
+
+Describe any substantial timing or memory changes: N/A
+
+Code reviewed by: nusbaume
+
+List all files eliminated: N/A
+
+List all files added and what they do: N/A
+
+List all existing files that have been modified, and describe the changes:
+M       bld/namelist_files/use_cases/1850_cam_lt.xml
+M       bld/namelist_files/use_cases/1850_cam_mt.xml
+          - namelist modifications as specified in #1515
+
+M       cime_config/testdefs/testlist_cam.xml
+          - bump up time limit on test which ran out of wallclock time
+
+If there were any failures reported from running test_driver.sh on any test
+platform, and checkin with these failures has been OK'd by the gatekeeper,
+then copy the lines from the td.*.status files for the failed tests to the
+appropriate machine below.  All failed tests must be justified.
