+ *
+ * 1. M261_mem.h is created for centralizing memory configuration. It will be included by C/C++ files
+ *    and linker files (except IAR linker file).
+ * 2. IAR linker doesn't support preprocessor, so M261_mem.icf.h, duplicate of M261_mem.h
+ *    is created for IAR linker file.
+ * 3. To continue above, we name M261_mem.icf.h instead of M261_mem.icf because:
+ *    (1) Mbed OS build tool may mis-regard M261_mem.icf as the main linker configuration file.
+ *    (2) *.icf files may not be present in search directories for "include" directive. Per observation,
+ *        the search directories are inconsistent among normal example build and test code build. To address
+ *        it, we name M261_mem.icf.h instead because *.h files are always present in these builds
+ *       (already there or via copy).
