/* About M451_mem.h/M451_mem.icf.h
23+
*
24+
* 1. M451_mem.h is created for centralizing memory configuration. It will be included by C/C++ files
25+
* and linker files (except IAR linker file).
26+
* 2. IAR linker doesn't support preprocessor, so M451_mem.icf.h, duplicate of M451_mem.h
27+
* is created for IAR linker file.
28+
* 3. To continue above, we name M451_mem.icf.h instead of M451_mem.icf because:
29+
* (1) Mbed OS build tool may mis-regard M451_mem.icf as the main linker configuration file.
30+
* (2) *.icf files may not be present in search directories for "include" directive. Per observation,
31+
* the search directories are inconsistent among normal example build and test code build. To address
32+
* it, we name M451_mem.icf.h instead because *.h files are always present in these builds
33+
* (already there or via copy).
