1.00  drg/jz 01/25/10 First release.
3.7   asa    04/01/22 The selftest example uses the instance name as
                      "Spi" in the instance definition. That causes
                      issue when periphtest application is build for a
                      design that has a soft spi IP along with the
                      hard spips. This is fixed by renaming the
                      instance name from "Spi" to "SpiPs"
3.9   sb   07/05/23   Added support for system device-tree flow.
