4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Gonzalez marc.w.gonzalez@free.fr
commit 6e53330909672bd9a8c9f826e989a5945d9d9fdf upstream.
My console locks up as soon as Linux writes to [88800000,88f00000[ AFAIU, that memory area is reserved for trustzone.
Extend TZ reserved memory range, to prevent Linux from stepping on trustzone's toes.
