                        nochunk: disable reading files in "chunks" in the EFI
                        boot stub, as chunking can cause problems with some

                        attribute may cause the kernel to reserve the
                        memory range for a memory mapping driver to
                        claim. Specify efi=nosoftreserve to disable this
