 	* fs/fat:  Fix an error in the long file name logic:  If the long file name
 	  is an even multiple of 13 bytes in length, then it should not include a
 	  NULL terminating character.  Fix contributed by Kaushal Parikh.

+	* configs/sim/nx11 - Created a separate configuration to build the NX

+  This configuration uses the simple touchscreen test at

+#   time console output
+# CONFIG_MSEC_PER_TICK - The default system timer is 100Hz

+#   then this setting is the maximum number of higher priority
+#   threads (minus 1) than can be waiting for another thread
