Ya you are right. But there is fundamental difference b/w DT and Non-DT in linux
kernel.
If the boards like Begleboneblack can have two types of linux kernel sources.
1. without board specific file (board info provided by device tree
blob)
2. with board specific files
I think any one of this can only possible. When you boot the kernel with DT
support we cant find the
board specific files.

The only way visible to us is to include the #if #if IS_ENABLED(CONFIG_OF) for
of_match_ptr(at86rf230_of_match) also.
