This patch creates a new tune_param structure for Cortex-A15. The new tune is identical to the generic cortex tune used for Cortex-A15 before this patch, except the field prefer_ldrd_strd is set to true. This field will be used by subsequent patches, in particular for prologue/epilogue. Ok for trunk?
