Memory region IDT_LIST

Question

Hi. 
 What is IDT_LIST (Memory region)? 
 
 What is it used for and can it be used in nRF52820 microcontroller? 
 Thank you.

Hello, 
 It's the interrupt descriptor table / vector table. Based on description here, https://github.com/nrfconnect/sdk-zephyr/blob/main/include/zephyr/linker/intlist.ld#L22 , it's just a bogus memory region, that is stripped from the final ELF image.
