You are right. But time is a limited resource. And fixing cache related issues is a bit more complex then, for example, the simple changes needed when relocation was introduced in ARM. >> If d-cache will be enabled by default on ARM I think I have to send a >> patch for one of my boards :-) > > Why don't you just help identifying and fixing the problems in the > misbehaving drivers?!? > > That would be a _much_ more helpful approach. Well, that is what I meant. I have to fix the driver then. But this will interfere with the fact that time is a lim.... You know ;-) If both of my boards are in mainline I will take a look at them and try to fix problematic drivers (mainly USB OHCI should be the problem) Regards Matthias _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
