/* About M251_mem.h/M251_mem.icf.h
*
* 1. M251_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 M251_mem.icf.h, duplicate of M251_mem.h
* is created for IAR linker file.
* 3. To continue above, we name M251_mem.icf.h instead of M251_mem.icf because:
* (1) Mbed OS build tool may mis-regard M251_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 M251_mem.icf.h instead because *.h files are always present in these builds
* (already there or via copy).
