+This script is invoked by Make system and generates secure partition makefile.
+It expects platform provided secure partition layout file which contains list
+of Secure Partition Images and Partition manifests(PM).
+Layout file can exist outside of TF-A tree and the paths of Image and PM files
+must be relative to it.
+
+This script parses the layout file and generates a make file which updates
+FDT_SOURCES, FIP_ARGS and SPTOOL_ARGS which are used in later build steps.
+This script also gets SP "uuid" from parsing its PM and converting it to a
+standard format.
+
+param1: Generated mk file "sp_gen.mk"
+param2: "SP_LAYOUT_FILE", json file containing platform provided information
+param3: plat out directory
+
+Generated "sp_gen.mk" file contains triplet of following information for each
+Secure Partition entry
+    FDT_SOURCES +=  sp1.dts
+    SPTOOL_ARGS += -i sp1.bin:sp1.dtb -o sp1.pkg
+    FIP_ARGS += --blob uuid=XXXXX-XXX...,file=sp1.pkg
+
+A typical SP_LAYOUT_FILE file will look like
+{
+        "SP1" : {
+                "image": "sp1.bin",
+                "pm": "test/sp1.dts"
+        },
+
+        "SP2" : {
+                "image": "sp2.bin",
+                "pm": "test/sp2.dts"
+        }
+
+        ...
+}
