As mentioned above the main problem is the EMAC driver. It has either to be changed to support cache handling (invalidating/flushing) of the buffer descriptors. Or we must setup one small area in the SDRAM that is uncached and the driver uses this memory area for the buffer descriptors.
Other drivers may make similar assumptions.
For 44x, I don't think so.
You will have to run a pretty extensive set of regression testing (including other network drivers, USB, ...) when attempting to perform such a change.
Sure. This would be a major change and would need to be enabled in the board config file. And extensive testing of course.
Viele Grüße, Stefan
