Hi all,
This patch adds initial support for the Cortex-A32 core.
It is an ARMv8-A core and this patch enables the -mcpu=cortex-a32 and
-mtune=cortex-a32 options.
The initial tunings are set to the same parameters as for Cortex-A35.
Bootstrapped and tested on arm-none-linux-gnueabihf together with a binutils
suitably patched to recognise -mcpu=cortex-a32 and the respective .cpu directive
(https://sourceware.org/ml/binutils/2016-02/msg00345.html)
The build was configured with --with-cpu=cortex-a32 --with-mode=thumb
--with-fpu=neon-fp-armv8 --with-float=hard
Ok for trunk?
Thanks,
Kyrill
