MAKEALL logs are attached. Things are significantly worse after merging
the series. That's because of DaVinci boards using EMAC driver and
D-Cache enabled (I think this comes from times when D-Cache was disabled
by default on ARM9). With this
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/116671 patch
applied the results are almost the same as with master branch (see
after+patch.log).

Well, kernel uses coherent memory for descriptors and do
dma_map/dma_unmap on buffers. We don't have coherent memory support in
U-Boot so I just perform flush/invalidate for both descriptors and buffers.
