//**************************************************************** 

This patch affects PCIe Compiler reset circuitry for the HIP mode
Gen2:x4, Gen2:x8

   o The serdes reset controller described in the PCI Express user
     guide Figure 5-22 has been updated to address infrequent
     downtraining issues observed for the HIP mode Gen2:x4 and
     Gen2:x8.

   o There the 3ms reset circuit described in the design example and
   	 on page 151 of the User Guide is no longer needed.

   o The generated design example is updated to reflect the new reset
   	 circuit, and will no longer contains the 3 ms reset circuit

   o The variant port signature remains unchanged. 
      o This new reset circuit is backward compatible with the 3ms reset. 
      o The rx_freqlocked_one output of the PCIe variation used in the
      	design example's 3ms circuit is now permanently driven to
      	1'b1. If this 3ms circuit remains in place in the customer
      	design it will hold the HIP in reset 3ms longer than needed,
      	but that should not cause an issue.
