Prior to commit 93b283d49f93 ("ARM: CPU: arm926ejs: Consolidate cache routines to common file") the kirkwood boards didn't have and dcache support. The network and usb drivers rely on this.

Thanks for taking care of this. I agree, that such a generic approach to disable the d-cache (for now) is better than a board specific one. But could you please add a short comment to the header to describe the background, similar to this commit message here? Perhaps also with a note that some drivers need updating / fixing before this "workaround" can be removed again?
