Adding new boards to apio

Support a new board

In order to support a new board follow these steps:

1. Make sure your board (or FPGA) is supported by the OSS CAD Suite

2. Find or add your FPGA name in the fpgas.json file
   Ex:

"iCE40-HX1K-TQ144": {
  "type": "hx",
  "size": "1k",
  "pack": "tq144"
}

"iCE40-HX8K-CT256": {
  "type": "hx",
  "size": "8k",
  "pack": "ct256"
}

"iCE40-LP8K-CM81": {
  "type": "lp",
  "size": "8k",
  "pack": "cm81"
}

3. Find or add your programmer in programmers.json
   Ex:

"iceprog": {
  "command": "iceprog",
  "args": "-d i:0x${VID}:0x${PID}:${FTDI_ID}"
}

"icoprog": {
  "command": "export WIRINGPI_GPIOMEM=1; icoprog",
  "args": "-p <"
}

"tinyprog": {
  "command": "tinyprog",
  "args": "--pyserial -c ${SERIAL_PORT} --program",
  "pip_packages": [ "tinyprog" ]
}

4. If your programmer uses a python package, add this package and its version range to distribution.json
   Ex:

"pip_packages": {
  "blackiceprog": ">=2.0.0,<3.0.0",
  "litterbox": ">=0.2.1,<0.3.0",
  "tinyfpgab": ">=1.1.0,<1.2.0",
  "tinyprog": ">=1.0.21,<1.1.0"
}

5. Add your board to boards.json with the following format:

"icezum": {
  "name": "IceZUM Alhambra",
  "fpga": "iCE40-HX1K-TQ144",
  "programmer": {
    "type": "iceprog"
  },
  "usb": {
    "vid": "0403",
    "pid": "6010"
  },
  "ftdi": {
    "desc": "IceZUM Alhambra.*"
  }
}


"icoboard": {
  "name": "icoBOARD 1.0",
  "fpga": "iCE40-HX8K-CT256",
  "programmer": {
    "type": "icoprog"
  },
  "platform": "linux_armv7l"
}

"TinyFPGA-BX": {
  "name": "TinyFPGA BX",
  "fpga": "iCE40-LP8K-CM81",
  "programmer": {
    "type": "tinyprog"
  },
  "usb": {
    "vid": "1d50",
    "pid": "6130"
  },
  "tinyprog": {
    "desc": "TinyFPGA BX"
  }
}

6. Emitt a pull-request to the Apio develop branch
