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

[Holger Brunck]

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

    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
