Hi,
while looking at several U-Boot network drivers in the past year, I typically compared them to the sun8i-emac driver, as a kind of personal reference. While doing so, I figured that there are quite some things broken in here, and other things are not so nice. This series attempts the fix those shortcomings. Fix-wise we get proper handling of PHY failures (try without a cable connected), support for external RMII PHYs (as seen on the Pine64-non-plus model), and more future-proof internal PHY handling. The rest of the patches are cleanups, which fix things that are wrong, but we get away with so far, for one or another reason. This also cleans up a good part of the cache maintenance. There is more to be done (and I have patches for that), but that requires to drop the overzealous alignment checks in cache_v7.c first, which is part of another, upcoming series.
A git repo with those patches can be found here: https://github.com/apritzel/u-boot/commits/sun8i-emac-cleanup
Please have a look and send comments!
