From d3446b266a8c72a7bbc94b65f5fc6d206be77d24 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Fri, 17 May 2019 18:11:23 +0200 Subject: arm64: dts: marvell: mcbin: enlarge PCI memory window Running a graphics adapter on the MACCHIATObin fails due to an insufficiently sized memory window. Enlarge the memory window for the PCIe slot to 512 MiB. With the patch I am able to use a GT710 graphics adapter with 1 GB onboard memory. These are the mapped memory areas that the graphics adapter is actually using: Region 0: Memory at cc000000 (32-bit, non-prefetchable) [size=16M] Region 1: Memory at c0000000 (64-bit, prefetchable) [size=128M] Region 3: Memory at c8000000 (64-bit, prefetchable) [size=32M] Region 5: I/O ports at 1000 [size=128] Expansion ROM at ca000000 [disabled] [size=512K] Signed-off-by: Heinrich Schuchardt Signed-off-by: Gregory CLEMENT --- arch/arm64/boot/dts/marvell/armada-8040-mcbin.dtsi | 2 ++ 1 file changed, 2 insertions(+) (limited to 'arch/arm64/boot/dts/marvell/armada-8040-mcbin.dtsi') diff --git a/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dtsi b/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dtsi index 329f8ceeebea..205071b45a32 100644 --- a/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dtsi +++ b/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dtsi @@ -184,6 +184,8 @@ num-lanes = <4>; num-viewport = <8>; reset-gpios = <&cp0_gpio2 20 GPIO_ACTIVE_LOW>; + ranges = <0x81000000 0x0 0xf9010000 0x0 0xf9010000 0x0 0x10000 + 0x82000000 0x0 0xc0000000 0x0 0xc0000000 0x0 0x20000000>; status = "okay"; }; -- cgit
