/* About M451_mem.h/M451_mem.icf.h
 *
 * 1. M451_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 M451_mem.icf.h, duplicate of M451_mem.h
 *    is created for IAR linker file.
 * 3. To continue above, we name M451_mem.icf.h instead of M451_mem.icf because:
 *    (1) Mbed OS build tool may mis-regard M451_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 M451_mem.icf.h instead because *.h files are always present in these builds
 *       (already there or via copy).
