Bananapi M1 broken sd card detect pin

[niccodemi]

Hi,

 

I would like to run Armbian Stretch  (mainline kernel 4.14.y) on Bananapi M1. Board has an issue - sd card detect pin is broken. In legacy kernel 3.4.y  there was an easy workaround to change paramter sdc_detmode = 1 to sdc_detmode = 3 in /boot/script.bin file.

How would I do this on 4.14 kernel which as I understand doesn't use script.bin anymore?

I setup Virtualbox with Ubuntu 18.04 and I can compile image with default options. I only need guidance in what parameter and in which file to change.
