I need help from a xen expert.
I know that xen support for imx8qm has been droped, so I am trying to bring it back myself.
Aparrently when trying to load the kernel ( 6.6 ) xen (4.17) fails at this point:
(XEN) kernel_zimage_load: load_addr=00000000a8000000, paddr=000000009e000000, len=0000000002143200
I narrowed it down to the way it reads the RAM type:
(XEN) kernel_zimage_load: kernel mapped to 0000000040121000
(XEN) get_page_from_gfn: domain=00008002fffd6000, gfn=a8000, t=00000000002ecc3c, q=1

(XEN)
(XEN) ****************************************
(XEN) Panic on CPU 0:

Is there anybody who can guide me here? why is p2mt 5? it should be 1 or 0 i think.
