If you're on an ACPI platform, you're probably not using this IP. It's
really old and in need of an update (like what the "hard" version of
it got), we just happened to have some customers that wanted more SPI
controllers on the FPGA. I dunno if using these provider agnostic APIs
is something we should be doing where possible as good practise, but if
it's to make the IP more broadly usable I'd say that that's mostly
wasted effort.
