L2 cache with cortex-A8

Hello,

Can I assume that with cortex A8 cache invalidate/flush is used only with L1 ?
I have some 2 implementation of this routines, one is called L1 and the other L2C-310.

I am just not sure if using L1 will be good enough, or is it that cortex a8 internal L2 still need to be flushed/invalidate even when using cortex a8.

Thank you!
