I do not have a solution for the Bug issue, but I did something similar
on i.MX 7 as well using a reserved-memory entry, see:
https://blog.printk.io/2017/05/i-mx-7-cortex-m4-memory-locations-and-performance/
Its some months ago, but as far as I remember that worked fine.

Isn't that kind of contradicting since you take that exact area away
from Linux above?
