The memory area [0x4000000-0x4200000[ is occupied by the PSCI firmware. Any attempt to access it from Linux leads to an immediate crash. So let's make the same memory reservation as the vendor kernel. Signed-off-by: Heinrich Schuchardt <xypron.glpk@xxxxxx> --- v2 Move the change from armada-8040-mcbin.dts to armada-ap806.dtsi. I only have a MACCHIATObin for testing but https://github.com/MarvellEmbeddedProcessors/linux-marvell has the reservation in that file. --- arch/arm64/boot/dts/marvell/armada-ap806.dtsi | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/arch/arm64/boot/dts/marvell/armada-ap806.dtsi b/arch/arm64/boot/dts/marvell/armada-ap806.dtsi index 7d94c1fa592a..f8dafef83db0 100644 --- a/arch/arm64/boot/dts/marvell/armada-ap806.dtsi +++ b/arch/arm64/boot/dts/marvell/armada-ap806.dtsi @@ -28,6 +28,17 @@ method = "smc"; }; + reserved-memory { + #address-cells = <2>; + #size-cells = <2>; + ranges; + + psci-area@4000000 { + reg = <0x0 0x4000000 0x0 0x200000>; + no-map; + }; + }; + ap806 { #address-cells = <2>; #size-cells = <2>; -- 2.19.2
