I saw there is a patch serial that try to add tuning for ARMv8 a year
ago, but at that time, there is not much tune opinions, even the NEON
FPU is not optional in all the cortex.

But when the A35 comes and gcc support more opinions on them, I think it
is necessary to add support those thing in armv8.

I have no idea how to support those big.little combo, there is too much
pattern, I would like to only create tuning file for echo cortex IPs first.

This patch is just sending for early check, whether it would be welcome.

ayaka (3):
  [WIP]: arch-arm64.inc: allow soft fpu configure
  arch-armv8a.inc: add tune include for armv8
  tune-cortexa17: add tunes for ARM Cortex-A35
