This is a verilog test that makes the FOMU blink blue.

Its main goal here is to test the symbiflow toolchain with two different blink
firmwares, one is the reference verilog-blink from the FOMU workshop
project[1], and this one has been modified from that project to only blink
blue.

Blue was chosen as:
- The default verilog-blink blinks all the colors sequencially, so if we do
  something similar, it wound't be easy to distinguish between both.
- The stock bootloader blinks green, so green needs to be avoided to
  distinguish both states.
- In several cultures (but not in all of them), red is commonly used to
  indicate some error conditions, so we avoided it as well.
