-/**
- * The default implementation of _sbrk() (in common/retarget.cpp) for GCC_ARM requires one-region model (heap and stack share one region), which doesn't
- * fit two-region model (heap and stack are two distinct regions), for example, NUMAKER-PFM-NUC472 locates heap on external SRAM. Define __wrap__sbrk() to
- * override the default _sbrk(). It is expected to get called through gcc hooking mechanism ('-Wl,--wrap,_sbrk') or in _sbrk().
