DMA is code complete, but untested. Known issues: 1. For 16-bit reads that are not aligned on a 4 byte boundary, the dma_unit should read the data from the upper 16-bits of the rdata bus. Currently the dma_unit always reads from the lower bits of rdata.

* Initial commit of DMA. DMA is code complete, but untested. Known issues: 1. For 16-bit reads that are not aligned on a 4 byte boundary, the dma_unit should read the data from the upper 16-bits of the rdata bus. Currently the dma_unit always reads from the lower bits of rdata. * Did the reasonable thing and made a directory for dma * created project to hook up to BRAM, push entire project * basic dma transfer with test * change size of mem access * dma looks like it works, writing tests * pases until incremental 16 bit read/write * added register defines to top * simulation passes * works except for reset * remove extra reset * coe file for dma_test * tb_fsm * add multiple irq lines * tested with 16 bit write to top and bott of word * removing vivado project * removed unused modules from lib * Chagned inout tri to input/output tri
