+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.

+Subject: [PATCH 2/2] rockchip: Disable binary generation for all SoCs.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+All supported Rockchip SoCs (RK3288, RK3328, RK3368 and RK3399)
+have non-continuous memory areas in the linker script with a huge
+gap between them. This results in extremely padded binary images
+with a size of about 4 GiB.
+
+E.g. on the RK3399 we have the following memory areas (and base addresses):
+RAM (0x1000), SRAM (0xFF8C0000), and PMUSRAM (0xFF3B0000).
+
+Consumers of the TF-A project (e.g. coreboot or U-Boot) therefore
+use the ELF image instead, which has a size of a few hundred kBs.
+
+In order to prevent the generation of a huge and useless file,
+this patch disables the binary generation for all affected Rockchip
+SoCs.
