A memmap is a directory in sysfs which includes 3 text files: start, end and type. For example: start: 0x100000 end: 0x7e7b1cff type: System RAM Interface firmware_map_add was not called explicitly. Remove it and add function firmware_map_add_hotplug as hotplug interface of memmap. Each memory entry has a memmap in sysfs, When we hot-add new memory, sysfs does not export memmap entry for it. We add a call in function add_memory to function firmware_map_add_hotplug. Add a new function add_sysfs_fw_map_entry() to create memmap entry, it will be called when initialize memmap and hot-add memory.
