This patch implements the driver necessary use the Analog Devices Blackfin processor's on-chip ethernet MAC controller. [try#2] - add timeout control - kill dma_config_reg bitfields - some trivial cleanup [try#3] - add endianess check - add DRV_NAME, DRV_VERSION... driver information string - add some comments for silicon anomaly and dma API confusion - some code trivial cleanup [try#4] - add Blackfin latest GPIO pin mux opertion with Michael Hennerich's help and Dan's review - rewrite the DMA descriptor list operation in a more readable way by Joe's review [try#5] - cleanup some coding style by Joe's review. [try#6] - 1.1 version fix a bug when set up multicast list pointed by Mr. yoshfuji - rearrange the desc_list_free function.
