[U-Boot-Users] FPGA configuration using SPI?

[w.wegner at astro-kom.de]

Hi everybody,

I am rather new to U-Boot but finally got it running on our custom MCF5373L board. (Thanks 
to Robert S Grimes, who gave some very vital hints!) Now I want to start FPGA configuration 
via SPI for a Xilinx Spartan3 and an Altera Cyclone device.

As far as I understand the code, this is not directly supported and does not fit in the current 
scheme (when faking slave parallel mode, the additional clock pulse generation would be a 
problem). So IMHO extending the modes with something like "slave serial SPI" would be the 
cleanest solution.

Did anybody do something like this already, or are there any other hints?

Thank you and best regards,
Wolfgang
