Xilinx Slave Serial SPI FPGA Manager
-Xilinx Spartan-6 FPGAs support a method of loading the bitstream over
-what is referred to as "slave serial" interface.
+Xilinx Spartan-6 and 7 Series FPGAs support a method of loading the
+bitstream over what is referred to as "slave serial" interface.
The slave serial link is not technically SPI, and might require extra
circuits in order to play nicely with other SPI slaves on the same bus.
