- * Name: up_allocate_heap
- *
- * Description:
- * This function will be called to dynamically set aside the heap region.
- *
- * For the kernel build (CONFIG_NUTTX_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().
- *
- * The following memory map is assumed for the flat build:
- *
- * .data region. Size determined at link time.
- * .bss region Size determined at link time.
- * IDLE thread stack. Size determined by CONFIG_IDLETHREAD_STACKSIZE.
- * Heap. Extends to the end of SRAM.
- *
- * The following memory map is assumed for the kernel build:
- *
- * Kernel .data region. Size determined at link time.
- * Kernel .bss region Size determined at link time.
- * Kernel IDLE thread stack. Size determined by CONFIG_IDLETHREAD_STACKSIZE.
- * Padding for alignment
- * User .data region. Size determined at link time.
- * User .bss region Size determined at link time.
- * Kernel heap. Size determined by CONFIG_MM_KERNEL_HEAPSIZE.
- * User heap. Extends to the end of SRAM.
