Re: [PATCH v2] ARM: omap2: hide omap3_save_secure_ram on non-OMAP3 builds

> In configurations without CONFIG_OMAP3 but with secure RAM support,

> arch/arm/mach-omap2/omap-secure.o: In function `omap3_save_secure_ram':
> omap-secure.c:(.text+0x130): undefined reference to `save_secure_ram_context'
> The omap3_save_secure_ram() function is only called from the OMAP34xx
> power management code, so we can simply hide that function in the
