This patch adds a new driver for the GRSPW SpaceWire AMBA interface family. The new driver does not implement a standard RTEMS driver, instead it provides only a library interface to the GRSPW devices. This driver can be used to implement a RTEMS I/O driver or used directly. New features compared with old GRSPW driver: * zero-copy packet interface * possibility to send/receive mulitple packets per call * optional interrupt awaken work-task to process TX/RX queues * DMA channels support. Before only first DMA channel supported * Separate DMA and link control * Packet based error flags
