The main function of the DMA controller is the transfer of data from/to any DPlus compliant peripheral to/from the memory. A memory to memory copy capability can also be configured. This ldma driver is used for configure the device and channnels for data and control paths. These controllers provide DMA capabilities for a variety of on-chip devices such as SSC, HSNAND and GSWIP. ------------- Future Plans: ------------- LGM SOC also supports Hardware Memory Copy engine. The role of the HW Memory copy engine is to offload memory copy operations from the CPU.
