[PATCH 53/61] 82xx: Set NOT_COHERENT_CACHE on 8272 with PCI.

From: Scott Wood <hidden>
Date: 2007-07-18 01:36:17
Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Linus Torvalds

I've seen significant network corruption on a PCI network
card (e1000) with the mpc8272ads; the corruption went away
when I set CONFIG_NOT_COHERENT_CACHE.
