After reading the fdt u-boot overwrites the reg property of the memory node with <0x0 0x0 0x0 0x78000000>. To override this setting we have to use the property linux,usable-memory. If the first 16MB of the 2GB physical memory are used by the Linux kernel oops occur on the Odroid C2. For the Odroid C2 this patch replaces [RFT PATCH] ARM64: dts: meson-gxbb: Add reserved memory zone and usable memory range https://lkml.org/lkml/2016/12/12/127 Fixes: 855960342d1e7 ARM64: dts: amlogic: add Hardkernel ODROID-C2 CC: Neil Armstrong <narmstrong@xxxxxxxxxxxx> CC: Kevin Hilman <khilman@xxxxxxxxxxxx> Signed-off-by: Heinrich Schuchardt <xypron.glpk@xxxxxx> --- arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts b/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts index 238fbeacd330..82ab94417940 100644 --- a/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts +++ b/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts @@ -61,7 +61,7 @@ memory@0 { device_type = "memory"; - reg = <0x0 0x0 0x0 0x80000000>; + linux,usable-memory = <0x0 0x01000000 0x0 0x7f000000>; }; usb_otg_pwr: regulator-usb-pwrs { -- 2.11.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
