Hi all,
This patchlet adds the part numbers for the Cortex-A53 and A57 cores so that
they can be detected when parsing /proc/cpuinfo on AArch32 Linux systems. This
will allow the -mcpu=native machinery to detect those cores.
Tested arm-none-eabi on a model.
This is a fairly innocuous change, is it ok at this stage or for next stage 1?
Thanks,
Kyrill
