Hi Russel,

I just sent a V3 to follow your remark.
If this is ok, l'll add it to your patch system.

Thanks for your review.

Patch is okay, but I think the commit message needs to be better :)

"Allow device tree to override the L2C prefetch settings, even when
l2x0_cache_size_of_parse() fails to parse the cache geometry due to (eg)
missing "cache-size" or "cache-sets" properties."

I think with something along those lines, the patch can be put in my
patch system for when I next get around to applying some kernel patches
instead of reading email. :)
