They are designed to protect shared hardware resources (e.g. I2C controller). Please refrain using them as a general purpose synchronization primitive for the tasks to avoid unintended slippery effects (e.g. priority inversion), use the provided message-passing functions instead for that purpose. The mutex variable (ie the "struct mutex") should be initially filled with 0, but this is the default compiler behavior if you declare it as a global variable.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.
