22 * An LPC Host Controller: Manages LPC functions such as host vs slave mode, the
23 physical properties of some LPC pins, configuration of serial IRQs, and
24 APB-to-LPC bridging amonst other functions.
26 * An LPC Host Interface Controller: Manages functions exposed to the host such
27 as LPC firmware hub cycles, configuration of the LPC-to-AHB mapping, UART
