==================

Added
-----

- hdl: new testbench to test the DMA feature (read/write to DDR memory) in the new golden.

Changed
-------

- hdl: Switch to 125MHz (from 62.5MHz before) clock for DMA transfers.
- hdl: Cleanup of top-levels, addition of DMA to the golden.

Fixed
-----

- hdl: DMA misalignment issue due to loss of 32-bit words, caused in turn by inadequate flow control.
- hdl: typo in synthesis constraints.
