Subject: Re: [PATCH v2 0/4] arm64: dts: rockchip: Add Hardkernel ODROID-M1S

Hi Jonas,

I applied your four patches for the Odroid M1S to the mainline kernel [1], 
compiled it using the kernel configuration from the Hardkernel Ubuntu 
Server Image [2], and then attempted to boot into the official Generic 
AArch64 image on mmcblk0 using a dtb file and an Arch Linux initrd by 
manually copying the kernel and dtb file to the boot partition and 
booting manually with the vendor's U-Boot [3]. 

The booting process was successful!

However, the network interface is not working. Here is the relevant 
dmesg output:

Does anyone have any idea what could be causing this issue, or if there 
is anything I could try to get the network interface up and running?

Thanks for your help!

Best regards,
Patrick
