no_coregen branch generic_fifo is buggy, not outputing the last written data
from time to time.
Was causing the gennum core to hang (waiting forever on the last data).

Tying to find the PC hang bug.

This was missing modification from the svn local copy...

Was using the external reset (from gn4124 chip) only.
Now it uses the system reset taking into account the external reset
and the system clockpll lock status.

Update Manifest to take the git versions of the ddr and gn4124 cores.

Because a migration to git is foreseen.

 -> generic to select interface mode (classic/pipelined) and address granularity (byte/word).
 -> wishbone address port size.

Now the interrupt is generated when the DDR interface write FIFO is empty.
This is to avoid read request from the host before all data are written to the DDR memory.

Add synthesis, p&r and timing reports.
Remove generated simulation files from repo.
