RSIZE_MAX_MEM limit

[sanchit-misra]

The following code in include/safe_mem_lib.h sets the maximum limit of memcpy to 256 MB.
#define RSIZE_MAX_MEM ( 256UL << 20 ) /* 256MB */

If we have larger copies, is it safe to increase the value of RSIZE_MAX_MEM or should we do it in multiple chunks?

Is there any reason why this limit is hardcoded as 256MB? Are there circumstances where it would not be safe to increase outside of insufficient memory?
