+Subject: [PATCH 1/2] build_macros: Add mechanism to prevent bin generation.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On certain platforms it does not make sense to generate
+TF-A binary images. For example a platform could make use of serveral
+memory areas, which are non-continuous and the resulting binary
+therefore would suffer from the padding-bytes.
+Typically these platforms use the ELF image.
+
+This patch introduces a variable DISABLE_BIN_GENERATION, which
+can be set to '1' in the platform makefile to prevent the binary
+generation.
