Tony,
Any chance of picking these up?
I see that next-20130701 is broke as well in an OMAP5 only build. beyond
the fixes already merged in - the missing series seems to be the
$subject series to allow an OMAP5 only build.

Hi,
Cortex-A15 based OMAP5 does not use Snoop Control Unit(SCU)[1].
However, there is lot of code that is shared between Cortex-A9 based
OMAP4 and OMAP5, hence functionality code is shared with runtime usage
of SCU based on SoC worked on. However on building with OMAP5 only
generates the following errors:
arch/arm/mach-omap2/built-in.o: In function `scu_gp_set':
arch/arm/mach-omap2/sleep44xx.S:132: undefined reference to `scu_power_mode'
arch/arm/mach-omap2/built-in.o: In function `scu_gp_clear':
arch/arm/mach-omap2/sleep44xx.S:229: undefined reference to `scu_power_mode'
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'
This was attempted to be "fixed" in various attempts in the past [2] [3].
This series applies on top of the other fixes in discussion for linux-next [4] [5].
Based on:
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git next-20130626
Nishanth Menon (2):
ARM: OMAP4: sleep: build OMAP4 specific functions only for OMAP4
ARM: scu: provide inline dummy functions when SCU is not present
