It's not so easy. I need some time to check how it will work. At least on CRIUS 
AIOP v2 we have dataflash connected to SPI interface.
Also SPI3 - uses Serial3 in SPI mode (maybe I'm wrong), but Serial3 used for 
Telemetry.

That's right. If ADNS3080 is connected to SPI (ICSP header) and pin 34 (CS) 
then dataflash need to be disabled. If it is connected to USART3 then telemetry 
needs to be disabled. Teoretically SPI can be shared between flash and optflow, 
using Chip-Select on SPI. I have only Crius AIOP 1.0 and 1.1 so I cannot test 
this right now.
