2012-08-23ARM: imx: build i.MX6 functions only when neededArnd Bergmann
The head-v7.S contains a call to the generic cpu_suspend function, which is only available when selected by the i.MX6 code. As pointed out by Shawn Guo, i.MX5 does not actually use any functions defined in head-v7.S. It is also needed only for the i.MX6 power management code and for the SMP code, so we can restrict building this file to situations in which at least one of those two is present. Finally, other platforms with a similar file call it headsmp.S, so we can rename it to the same for consistency. Without this patch, building imx5 standalone results in: arch/arm/mach-imx/built-in.o: In function `v7_cpu_resume': arch/arm/mach-imx/head-v7.S:104: undefined reference to `cpu_resume' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Shawn Guo <shawn.guo@linaro.org> Cc: Eric Miao <eric.miao@linaro.org> Cc: stable@vger.kernel.org

2011-12-31ARM: imx6: remove __CPUINIT annotation from v7_invalidate_l1Shawn Guo
The recent suspend testing on !SMP build discovers that the __CPUINIT annotation for v7_invalidate_l1 should not be there, as the function is called by resume path for not only SMP but also !SMP build. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2011-12-30ARM: imx6: fix v7_invalidate_l1 by adding I-Cache invalidationShawn Guo
The recent suspend/resume and reset testing on imx6q discovers that not only D-Cache but also I-Cache has random data and validity when the core comes out of a power recycle. This patch adds I-Cache invalidation into v7_invalidate_l1 to make sure both D-Cache and I-Cache invalidated on power-up. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
