+The build system provides a non configurable build option IMAGE_BLx for each
+boot loader stage (where x = BL stage). e.g. for BL1 , IMAGE_BL1 will be
+defined by the build system. This enables the Trusted Firmware to compile
+certain code only for specific boot loader stages
+
All assembler files have the `.S` extension. The linker source files for each
boot stage have the extension `.ld.S`. These are processed by GCC to create the
linker scripts which have the extension `.ld`.
