Tutorials for getting started with an f8 softcore on an FPGA board.

From blinking LEDs, via "Hello, world!" on a serial line to simple benchmarks.

As far as possible, for all boards a free toolchain is used.

Supported boards:

* iCEBreaker and UPduino 2
  Free board designs featuring the Lattice iCE40UP5K FPGA.
  A free toolchain (sv2v+yosys+nextpnr+icepack+iceprog) works well for these boards.
  The f8 works well, but the limited resources of the iCE40UP5K can be a restriction for some uses.

* GateMateA1-EVB
  A free board design featuring the Cologne Chip GateMate CCGM1A1 FPGA.
  Since a free toolchain (sv2v+yosys+nextpnr+icepack+iceprog) was not fully until recently, we still use a non-free P&R tool.
  The f8 works well.

Work in progress:

* Tang Nano 9K
  A board featuring the Gowin GW1NR-9 FPGA.
  The tutorial uses the free toolchain (sv2v+yosys+nextpnr+gowin_pack+).
  The f8 works well.
