adds flash support for Nuvoton M052, M054, M058, M0516 microcontrollers into the mini51 driver, patch also adds support for programing LDROM, flash data and flash config. I've tested it on a M0516LBN microcontroller using an ST-LINK/V2: 1. removing security lock: openocd -f interface/stlink-v2.cfg -f target/m051.cfg -c "init ; halt ; mini51 chip_erase; exit" 2. flashing: openocd -f interface/stlink-v2.cfg -f target/m051.cfg -c "program file.hex" Change-Id: I918bfbb42461279c216fb9c22272d77501a2f202 Signed-off-by: Pawel Si <stawel+openocd@gmail.com> Reviewed-on: http://openocd.zylin.com/2426 Tested-by: jenkins Reviewed-by: Nemui Trinomius <nemuisan_kawausogasuki@live.jp> Reviewed-by: Paul Fertser <fercerpav@gmail.com>
