The purpose of this library is to create an interface to communicate with the platform micro-controller. It abstracts the communication protocol (eg: SPI, UART, etc) between the application processor and the micro-controller. ArmPlatformPkg/ArmVExpressPkg: Implement ArmPlaformSysConfigLib This implementation allows to communicate with the microcontroller of the Versatile Express motherboard. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11785 6f19259b-4bc3-4df7-8a09-765794883524
