   o AMD MDB specific driver data
   o AMD specific VSEC capabilities to retrieve the base of
     phys address of MDB side DDR
   o Logic to assign the offsets to LL and data blocks if
     more number of channels are enabled than configured
     in the given pci_data struct.

 - Addition of non-LL mode
   o The IP supported non-LL mode functions
