+Subject: [PATCH] imx: Create distinct pre-processed mkimage config files
+
+Each imx image is created by a separate sub-make and during this process
+the mkimage config file is run though cpp.
+
+The cpp output is to the same file no matter what imx image is being
+created.
+
+This means if two imx images are generated in parallel they will attempt
+to independently produce the same pre-processed mkimage config file at
+the same time.
+
+Avoid the problem by making the pre-processed config file name unique
+based on the imx image it will be used in.  This way each image will
+create a unique config file and they won't clobber each other when run
+in parallel.
+
+This should fixed the build bug referenced in b5b0e4e3 ("imximage:
+Remove failure when no IVT offset is found").
