Use UART DFU implementation in Atmel for upload to nRF51

Hi. I would like upload firmware from Atmel microcontroller to nRF51822 with SD130. I suppose that I have to use single_bank_serial_s130 in nRF51822AA, but what I have to do on other side (Atmel side) ? I found this document, but I don't know if it is relevant for central device using SDK11 and SD130. Does exist any application for PC using bootloader over UART ?
