Board called DNA1 - there is no pictures available - only schematics. It has 46 chips, 2 banks of 23 each.
Board size is 80x80mm, I can add more banks if only I can run more SPI chains from RPi.
This is homegrown DIY project.

The idea is to use standard mining software with absolutely no modifications.
again ill ask: photograph of boards or identity of boards would be most helpful

How is this appears in RPi exactly?
Does cgminer require any code change to work with them?

Yes it would require code changes

Three of these:

and you good to go. You can split one SPI to eight. Of course you need to add some additional piece of code to driver.
this would work. http://www.digikey.com/product-detail/en/SN74CBTLV3251PWR/296-9129-1-ND/378104

From the sounds of it you have some BLackarrow bitfury boards sitting around and don't have a controller. Or similar product

I have multiple boards with SPI connection. Boards are populated with BFY chips.
How do I use more than 2 with RPi? I can not chain them together - there has to a way to reassign GPIO pins to use as CS.
You could implement SPI in software and allocate a different GPIO pin for each chip select. Doing SPI in software isn't difficult per se.
Guys,

Any ideas?
