Subject: [PATCH 12/12] powerpc/8xx: Remove cpu dependent macro instructions from head_8xx
Date: Tue,  8 Aug 2017 13:59:02 +0200 (CEST)	[thread overview]
Message-ID: <66f1ce3afcc79a8828ada3cebec8f6278b874ab2.1502191399.git.christophe.leroy@c-s.fr> (raw)
In-Reply-To: <cover.1502191399.git.christophe.leroy@c-s.fr>

head_8xx is dedicated to 8xx so no need to use macros that
depends on the CPU
