For 7-series FPGA UG470 mentions following guidelines for delaying FPGA configuration with SPI Flash:
For direct programming flash you need to use third party spi flash programmer as 7-series FPGA support indirect flash programming only.
I need a safe way to disable FPGA config outputs (to access SPI config memory) > FPGA will not sent configuration commands to SPI untill INIT_B goes high.
