C667x boot via DM3730

How do I boot the C667x multi-core DSPs from the DM3730?  The SPRUGY5 suggests to use the HyperLink boot mode. 
 1. How do I map the HyperLink interface to the DM3730?  
 2. Are the drivers for the HyperLink interface on the C667x and on the DM3730 available?
 3. Are the drivers TSIP, SPI, SRIO, and EMIF16 for the C667x available?
