-function. We pass the memory block type - `memory`, the physical base address and the size of the memory region, the maximum number of nodes which is 1 if `CONFIG_NODES_SHIFT` is not set in the configuration file or `1 << CONFIG_NODES_SHIFT` if it is set, and the flags. The `memblock_add_range` function adds a new memory region to the memory block. It starts by checking the size of the given region and if it is zero it just returns. After this, `memblock_add_range` checks the existence of the memory regions in the `memblock` structure with the given `memblock_type`. If there are no memory regions, we just fill new a `memory_region` with the given values and return (we already saw the implementation of this in the [First touch of the linux kernel memory manager framework](https://0xax.gitbooks.io/linux-insides/content/Initialization/linux-initialization-3.html)). If `memblock_type` is not empty, we start to add a new memory region to the `memblock` with the given `memblock_type`.
