[U-Boot] "armv7: integrate cache maintenance support" breaks km_kirkwood ethernet

Hi Aneesh, today I did a rebase of my development branch to current u-boot master. And I saw on our km_kirkwood board that our egiga0 interface isn't working anymore.

The CPU is a: SoC: Kirkwood 88F6281_A0

After bisecting the current tree I got:

c2dd0d45540397704de9b13287417d21049d34c6 is the first bad commit commit c2dd0d45540397704de9b13287417d21049d34c6 Author: Aneesh V aneesh@ti.com Date: Thu Jun 16 23:30:49 2011 +0000

armv7: integrate cache maintenance support

And indeed after reverting this commit on current HEAD my board is usable again.

Any ideas how to fix this problem?

Best regards Holger Brunck
