Put relocatable vectors at fixed address


Relocatable vectors location
└─>Put relocatable vectors at fixed address
In linux kernel since version 5.1 (release Date: 2019-05-05)  
This option puts relocatable vectors at specific virtual address.
Vectors are merged with the .init data in the kernel image and
are copied into their designated location during kernel startup.
Use it to put vectors into IRAM or out of FLASH on kernels with
XIP-aware MTD support.
