The early_fdt_scan_reserved_mem() function is used to scan through the DT and mark all the reserved memory regions as reserved or nomap as needed, as well as allocate the memory required by the dynamically-placed reserved memory regions. The second stage of the reserved memory processing is done by fdt_init_reserved_mem(). This function is used to store the information of the statically-placed reserved memory nodes in the reserved_mem array as well as call the region specific initialization function on all the stored reserved memory regions. The call to fdt_init_reserved_mem() is placed right after early_fdt_scan_reserved_mem() because memblock allocated memory should already be writable at this point.
