ARMADA100 is still ARMv5? Then maybe you can try Hong Xu's patches
for
dcache on armv5. You'll have to modify the ethernet driver to be aware of
the
dcache then though.
As dcache support is on the way, it might be worth it.
Yes ARMADA100 is ARMv5. I had problems with dcache enabled, driver
get
stuck. Can you please link me to Hong Xu's patches? Is there a
problem if
i keep it disabled?
http://lists.denx.de/pipermail/u-boot/2011-August/098405.html Look around this. You'd better search for V2 of the patches or V3 in U-Boot ML archive.
There's no problem if you keep it disabled, but eventually, you'll have to enable it ;-)
Cheers
Hi Marek,
I searched mail list after I emailed you.. There has been a lot of discussion going on Hong Xu's patches. I think it would be better if I work on enabling dcache once the patch is mainlined.
Thanks, Ajay Bhargav

You can always give it a whirl to test the patch. You can also find pieces of your driver that will need redesign because of the cache-line alignment and avoid such trouble in advance. But this is just an offer, it's not a firm requirement for the patch to be mainlined!
Cheers
