[PATCH] [AArch64] Basic Sched Model for Cortex-A57

[Renato Golin]

Hi Dave,

Thanks for working on the scheduling. I'll let Tim and others review the times, but having this is a good beginning.

Though, you could have some more tests, or is that the only difference we know so far is on the SDIV?

cheers,
