Thunderbolt not working with displays on coreboot 26.03

[Magnitaizer]

• Model: lemp13
• Not working on ec232d7 commit (Update to coreboot 26.03)
• Working on dfc6656 commit

So I have flashed latest firmware-open (ec232d7) on my lemp13 laptop

Then at work and at home 2 separate ugreen type-c adapters no longer connect 2nd display.

Doesn't matter of the OS , tried to load from usb, on debian live 13.4-gnome and pop os 24.04 live, still no screen.

When i have reverted to dfc6656 commit and re-flashed lemp13 screen through thunderbolt now is working correctly again. (Basic HDMI worked in both cases, just the thunderbolt port was affected)

Check out src/mainboard/system76/mtl/variants/lemp13/gpio.c from system76-25.03.

I have to look into why it's so different from what was upstreamed.
