This node seems slightly misplaced. Is there some external bus interface
that this is connected to? The address suggests that it should be somewhere
below the /soc node, and you probably want to list the external bus
interface with a "ranges" property that identifies the addresses visibile
there, and put the external chip under there.

I might messed it up since the MAC/PHY connects to the same 16-bit
interface as the 16MB PSRAM external memory and both connected via AHB.

Not sure how it should be expressed, so some help form DT camp would be
appreciated.

Cheers
Vladimir
