be claimed, otherwise the whole DE2 space is inaccessible.

Add a device tree binding of the DE2 part as a sub-bus.

Where did you get the info that it was a bus?

There's no direct evidence, just some guess.

The DE2 is a whole part that is just allocated a memory
space at the user manual, and the SRAM controls the
access to all modules in the DE2.

So it might be a bus.

Implement it as a bus is a clear representation on A64.
