Hi all,
This patch adds initial support for the Cortex-A73 processor through the
cortex-a73, cortex-a73.cortex-a35 and cortex-a73.cortex-a53 arguments to -mcpu
and -mtune.
The Cortex-A73 is an ARMv8-A processor and the initial tuning is based on
the Cortex-A57 tuning (though not an exact copy).
Bootstrapped and tested on aarch64-none-linux-gnu with an appropriately
patched binutils that understands the relevant -mcpu argument.
Ok for trunk?
Thanks,
Kyrill
