-// FF mapping for Spartan 6.  The primitives used are the same as Series 7,
-// but with one major difference: the initial value is implied by the
-// primitive type used (FFs with reset pin must have INIT set to 0 or x, FFs
-// with set pin must have INIT set to 1 or x).  For Yosys primitives without
-// set/reset, this means we have to pick the primitive type based on the INIT
-// value.
