Board/Platform Support
Board (platform) support implements necessary configuration of CPU and
platform (interrupt controller, system controllers, timers) in order to
initialize the rest of OS components and user tasks. This component
implements architecture and platform dependent part of task creation
and switching,
timers and time initialization, interrupt entry points, system flags
and states (enable/disable interrupts, caching), interrupt masking and
more.
Currently supported architectures and platforms include:
