* Name: up_allocate_heap
*
* Description:
* This function will be called to dynamically set aside
* the heap region.
*
* For the kernel build (CONFIG_BUILD_KERNEL=y) with both
* kernel- and user-space heaps (CONFIG_MM_KERNEL_HEAP=y),
* this function provides the size of the unprotected,
* user-space heap.
*
* If a protected kernel-space heap is provided, the kernel
* heap must be allocated (and protected) by an analogous
* up_allocate_kheap().
