[PATCH v5 01/13] ARM: move cputype definitions into another file

From: MylÃne Josserand
Date: Tue Apr 03 2018 - 02:22:48 EST


To add the support for SMP on sun8i-a83t, we will use some
definitions in an assembly file so move definitions into
another file to separate C functions and macro defintions.
