Returns the system stack and heap parameters. The values returned are typically those used by the C library during initialization. For RVISS, the values returned are those provided in peripherals.ami. For RealView ICE, the values returned are the image location and the top of memory.

The C library can override these values. See Tailoring storage management in the Libraries and Floating Point Support Guide for more information about memory management in the C library.

The host debugger determines the actual values to return by using the top_of_memory debugger variable.
