I have a custom IMX6ULL based board with two serial SPI flash: one of them connected by ECSPI1, another - ECSPI2.

ECSPI1 selected as boot interface by gpio and it boots well. But now I want to boot from ECSPI2 to get camera interface pins available but there is no option to select ECSPI2 as we don't have boot mode choosing resistors on board (boot mode selection gpios connected directly to GND and/or VCC without optional resistors).

Is there any way to boot from ECSPI2 in such case?

Thank you.
