ARM: rockchip: select ARMv7 compiler flags for platsmp.o
From: Heiko Stuebner <heiko@...> Date: Wed, 23 Jul 2014 11:36:49 +0200
Commit-Message
When compiling for multiplatform for both ARMv6 and ARMv7, the default compiler flags are for ARMv6, and the following cpu-hotplug change will fail with: /tmp/ccSFxfmI.s:68: Error: selected processor does not support ARM mode `isb ' /tmp/ccSFxfmI.s:74: Error: selected processor does not support ARM mode `isb ' /tmp/ccSFxfmI.s:75: Error: selected processor does not support ARM mode `dsb ' Fix this in a similar manner as in commit 9f0affcf3e21 "ARM: mvebu: Fix pmsu compilation when ARMv6 is selected", by specifying ARMv7 flags for platsmp.o. Signed-off-by: Heiko Stuebner <heiko@...>
