Description

Feedback from Andrey Abramov:

While testing I found out that if l2p_rdy_i deasserted ( please see l2p_dma_master.vhd ) the core hung the PC. It happend with 64-bit addresses.
The problem was that data counter (l2p_data_cnt) and ldm_arb_valid_o worked incorrectly when l2p_rdy_i deasserted.
I've corrected the problem so it doesn't occur any longer on my PC. I have not done an extensive testing though.
You can take a look at the enclosed modifided l2p_dma_master.vhd to see the changes made.
