Hi Russell
The backwards compatibility is for the ZII devel C, the DSA link
between the two switches? I don't think there are any other boards
using this.
I will ask around, but i don't think we need to worry about backwards
compatibility. There is no region of flash set aside for the DT blob,
etc. I always TFTP boot using the one from the kernel, etc.
