Did I miss the DT part somewhere or is that not part of this patch ?
As we are just barely starting from reset, there is no luxury of DT.
After this, DT will be used with the cache flush patch.
Another question I have is -- why don't we set CONFIG_SYS_{I,D}CACHE_SIZE to
maximum value? This should work for all nios2 cache configurations and it should
also be correct, no ? Speed might be a bit of an issue here, but I doubt the
impact would be that large.
I am doing all the best to get rid of the CONFIG_SYS_{I,D}CACHE_SIZE...
So I avoid to use the same macro names. Here I use the maximum value in
this startup only. The speed penalty is only once here. After we get DT
initialized, we have the correct values of cache configuration.
It might be awful to use the maximum value all the time. See, we flush
cache for every eth packet!
Thanks a lot for your review.
Best regards,
Thomas
