Now the script supports more flashing methods: - JLink (with tockloader) - OpenOCD (with tockloader) - pyOCD - Nordic DFU - none (will produce an IntelHex file) Also merged the contributions from: - Yihui Xiong to support the Makerdiary USB dongle board - Dennis Geurts to support Nordic DFU Doc updated accordingly. Imported 2 patches for Tock kernel: - 06-add-set_vector_table_offset.patch (upstream tock/tock#1579) - 07-nrf52-bootloader.patch (upstream tock/tock#1681)
