On platforms such as Cortex-A15 based OMAP5, SCU is not used, however since much code is shared between Cortex-A9 based OMAP4 (which uses SCU) and OMAP5, It does help to have inline functions returning error values when SCU is not present on the platform. arch/arm/mach-omap2/omap-smp.c which is common between OMAP4 and 5 handles the SCU usage only for OMAP4. This fixes the following build failure with OMAP5 only build: arch/arm/mach-omap2/built-in.o: In function `omap4_smp_init_cpus': arch/arm/mach-omap2/omap-smp.c:185: undefined reference to `scu_get_core_count' arch/arm/mach-omap2/built-in.o: In function `omap4_smp_prepare_cpus': arch/arm/mach-omap2/omap-smp.c:211: undefined reference to `scu_enable' Reported-by: Pekon Gupta <pekon@ti.com> Reported-by: Vincent Stehlé <v-stehle@ti.com> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com> |
