This breaks PowerPC boards.


Can you tell me how?

AFAIK, blocksize needs to be a multiple of 512 so this should be cache-safe with
any cacheline size.

A cast is missing, a warning is generated.


Yep. I recognized that right **after** I hit <send>...

If you can give me some guidance on the comment above, I'll address with a V2.
