From b1923caa6e641f3d0a93b5d045aef67ded5aef67 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 5 Jul 2016 15:07:51 +1000 Subject: powerpc: Merge 32-bit and 64-bit setup_arch() There is little enough differences now. mpe: Add a/p/k/setup.h to contain the prototypes and empty versions of functions we need, rather than using weak functions. Add a few other empty versions to avoid as many #ifdefs as possible in the code.
