+Subject: [PATCH] Remove duplicate configuration parameters for corstone-1000
+
+The PS_NUM_ASSET is duplicated in the cmake.config and the
+config_tfm_target.h file under corstone-1000. The commit removes
+the one from the cmake.config and keeps the one in the header file.
+
+The whole rationale behind this is for the vendor to be able
+to override the configuration using the cmake file.
