    Subject[PATCH 4.20 86/88] arm64: dts: qcom: msm8998: Extend TZ reserved memory area
    Date
    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.
