Subject: arm: mvebu: Fix compile for multiplatform when ARMv6 is selected
Date: Fri, 11 Jan 2013 12:05:31 -0800 [thread overview]
Message-ID: <20130111200531.GO14149@atomide.com> (raw)
Some systems compile in both ARMv6 and ARMv7 into multiplatform
configurations. This means the default compiler flags are for ARMv6,
and we will get:
arch/arm/mach-mvebu/coherency_ll.S: Assembler messages:
arch/arm/mach-mvebu/coherency_ll.S:45: Error: selected processor does not support `dsb'
Fix this by specifying ARMv7 flags for coherency_ll.o.
