Placing the stack and heap

The scatter-loading mechanism provides a method for specifying the placement of the stack and heap in your image.

The application stack and heap are set up during C library initialization. You can tailor stack and heap placement by using the specially named ARM_LIB_HEAP, ARM_LIB_STACK, or ARM_LIB_STACKHEAP execution regions. Alternatively, if you are not using a scatter file, you can re-implement the __user_setup_stackheap() function.
