    Subject[PATCH 5.10 01/71] ARM: boot: dts: bcm2711: Fix HVS register range
    Date
    From: Maxime Ripard <maxime@cerno.tech>

    [ Upstream commit 515415d316168c6521d74ea8280287e28d7303e6 ]

    While the HVS has the same context memory size in the BCM2711 than in
    the previous SoCs, the range allocated to the registers doubled and it
    now takes 16k + 16k, compared to 8k + 16k before.

    The KMS driver will use the whole context RAM though, eventually
    resulting in a pointer dereference error when we access the higher half
    of the context memory since it hasn't been mapped.
