Because kernel doesn't have yet an Ethernet driver for Meson GXBaby to set the platform-specific registers needed to program the MII mode, clocks and other things (the settings that are in patch 9/9 of this submission). And without documentation it's hard to write one and get it right. So this patch adds a new uboot-only node to the DTS for Ethernet. This doesn't seem problematic to me WRT synchronization with kernel DTS because no new bindings or driver changes are needed; and whenever the same node will be added to kernel we'll only have to update it in u-boot. If it is not acceptable to have a DTS different to kernel one, I'll have to find a different solution, any suggestions? Should I use U_BOOT_DEVICE and platform_data inside the board file instead? Maybe I will submit v3 of the series without Ethernet while I figure out this.
