The preferred way for I/O access is documented in [1], see "Use structures for I/O access" section.
This seems to not scale and I keep running into the problem where a few registers changed between various mutations of the IP more and more often.
This seems to be the case here too.
The maintainers of these drivers should decide what is better here.
Then I guess we go for the macros, since the structures don't work in the SoCFPGA case after all ?
I'm prefer using macros than struct. 1. We don't need to add unused registers. 2. Some registers are not continuous, adding padding is wasting space. 3. Easily reuse in different platform that only have few registers differences.
