Fix both. This was tested on a sl28 board. To force ECC errors, you can use the error injection supported by the controller in hardware (with CONFIG_EDAC_DEBUG enabled): # enable error injection $ echo 0x100 > /sys/devices/system/edac/mc/mc0/inject_ctrl # flip lowest bit of the data $ echo 0x1 > /sys/devices/system/edac/mc/mc0/inject_data_lo Fixes: 8897f3255c9c ("arm64: dts: Add support for NXP LS1028A SoC") Signed-off-by: Michael Walle Signed-off-by: Shawn Guo Signed-off-by: Sasha Levin --- arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi b/arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi index 262fbad8f0ec..1b264e5e947a 100644 --- a/arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi +++ b/arch/arm64/boot/dts/freescale/fsl-ls1028a.dtsi @@ -201,8 +201,8 @@ ddr: memory-controller@1080000 { compatible = "fsl,qoriq-memory-controller"; reg = <0x0 0x1080000 0x0 0x1000>; - interrupts = ; - big-endian; + interrupts = ; + little-endian; }; dcfg: syscon@1e00000 {
