Dear Joakim Tjernlund,
Hello Marek,

This patch conditionally defines flush_dcache_range() and invalidate_dcache_range() on MPC8xxx, to avoid EHCI complaining,
resulting in the following output:

+void flush_dcache_range(unsigned long start, unsigned long stop) +{ +}
Don't mind if this is a stupid question. Can't this be placed in some common header? Just to avoid code duplication!
And why are they just dummy functions? There are cache flush instructions for ppc
Doesn't the PPC have it's own internal snooping?
Best regards, Marek Vasut
