Zephyr drivers for SPI and GPIO were updated recently to allow ARC to directly access GPIO including AON_GPIO and SPI. You do not need x86 at all.
Please see the updated driver and sample app for BMI160 (top of the free, master).
Thanks Baohong

Hi
We have connected an Accelerometer to the x86 core of C1000 (Quark_se) through SPI interface. Interrupt line of accelerometer is also connected to the AON_GPIO_3
Now I need to route the SPI connection of x86 to Arc core. Is that possible ?
Any sample code in zephyr I can refer for this activity ?
