Hi, This is the driver for Xilinx AXI Video Direct Memory Access Engine. It is a soft IP core, which provides high-bandwidth direct memory access between memory and AXI4-Stream video type target peripherals including peripherals which support AXI4-Stream Video Protocol. The core provides efficient two dimensional DMA operations with independent asynchronous read and write channel operation. For more information on the IP, please refer to http://www.xilinx.com/support/documentation/ip_documentation/axi_vdma/v6_1/pg020_axi_vdma.pdf This patch also provides a test client, which assumes read and write channels of the core are configured in a back-to-back connection. It transfers data on the write channel, read and verify the data on the read channel. Use cases: ++++++++++ 1. Xilinx Video Targeted Reference design http://www.wiki.xilinx.com/Zynq+Base+TRD+14.5 2.
