Nick, I am seeing this issue on da830/da850/dm36x/dm644x.
I agree that u-boot will be faster with cache enabled. And also, TI wants it to be enabled soon. Since so many patches are lined u, we don't up-streaming them to get hampered because of this issue. So, we are trying to push this Patch. We are committed come up with appropriate patch to fix the EMAC and coherency issue. Meanwhile, we are trying to gather info about earlier patch/changes which disabled cache so that community understands the known issue. Also, one more engineer observed the issue with EMAC, I will send his mail to you.
