From a47a12becf66f02a56da91c161e2edb625e9f20c Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Thu, 15 Apr 2010 16:07:28 +0200 Subject: Move arch/ppc to arch/powerpc As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.
