Max1000 Remote System Upgrade via SPI

How interesting. The topic is Remote System Upgrade via SPI

However everybody switched to UART... May I make offtopic question and ask about discrete RSU via SPI (or I2C)?

From the very starting point - which IP block should I use for it?

The part I'm using is 10M08 with Verilog. I can translate from VHDL to Verilog, but original Verilog code is preferable.

There is a page with example for RSU via I2C but it does not help. Opening .par file shows only top file for 10M50 used as a I2C host. Structure of the project and used IP blocks are invisible

Besides the description of the project and how to run written for Quartus 16 and for a template it suggests to use an evaluation board that does not exist anymore.
