+Subject: [PATCH] makefiles: Drop setting -mcpu to cortex-a8 on arm
+ architecture
+
+We can not assume that all arches armv7+ are cortex-a8 only
+it fails to build for rpi which is armv7ve based (cortex-a8) cpu
+implementation.
+Fixes
+| cc1: warning: switch -mcpu=cortex-a8 conflicts with -march=armv7ve switch
+
+Upstream-Status: Pending
