Opencores SPI Controller Review

Recently, I had the opportunity to use a SPI controller from Opencores in a customer design based on an Intel PXA255 processor and a Xilinx CPLD.  The customer did not want to change the processor or the CPLD family, but needed an extra SPI interface in the device.  I had my doubts, but mentioned I would look into a SPI controller from Opencores.  To my surprise, the core fit in a Xilinx CPLD and worked out very well.  We have since upgraded to a Altera MAXII CPLD.  This review details this effort.
