2012-07-09ARM: OMAP5: Add SMP supportSantosh Shilimkar1-0/+21
Add OMAP5 SMP boot support using OMAP4 SMP code. The relevant code paths are runtime checked using cpu id Signed-off-by: R Sricharan <r.sricharan@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
2012-02-13ARM: omap: fix section mismatch warning for omap_secondary_startup()Russell King1-0/+1
WARNING: vmlinux.o(.text+0x1c664): Section mismatch in reference from the function omap_secondary_startup() to the function .cpuinit.text:secondary_startup() The function omap_secondary_startup() references the function __cpuinit secondary_startup(). This is often because omap_secondary_startup lacks a __cpuinit annotation or the annotation of secondary_startup is wrong. Unfortunately, fixing this causes a new warning which is harder to solve: WARNING: arch/arm/mach-omap2/built-in.o(.text+0x5328): Section mismatch in reference from the function omap4_hotplug_cpu() to the function .cpuinit.text:omap_secondary_startup() The function omap4_hotplug_cpu() references the function __cpuinit omap_secondary_startup(). This is often because omap4_hotplug_cpu lacks a __cpuinit annotation or the annotation of omap_secondary_startup is wrong. because omap4_hotplug_cpu() is used by power management code as well, which may not end up using omap_secondary_startup().

2011-12-08ARM: OMAP4: Remove __INIT from omap_secondary_startup() to re-use it for hotplug.Santosh Shilimkar1-5/+0
Remove the __INIT from omap_secondary_startup() so that it can be re-used for CPU hotplug. While at this, remove the un-used AUXBOOT register reference.

2011-03-09ARM: omap4: Convert END() to ENDPROC() for correct linkage with CONFIG_THUMB2_KERNELDave Martin1-1/+1
Code marked with ENTRY() also needs a matching ENDPROC() directive, in order to ensure that the type and instruction set of the symbol are correctly annotated. ENDPROC() tags the affected symbol as a function symbol, which will ensure that link-time fixups don't accidentally switch to the wrong instruction set.

2010-08-02omap4: Add smc API to read AuxCoreBoot0 registerSantosh Shilimkar1-16/+0
This patch adds a secure API to read AuxCoreBoot0 register to check the cpu boot status. It also moves the other smc APIs to common omap44xx-smc.S. This APIs should not be marked as __INIT because we need these to be present for CPU hotplug Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2009-06-09ARM: OMAP4: SMP: Add OMAP4430 SMP board filesSantosh Shilimkar1-0/+46
This patch adds SMP platform files support for OMAP4430SDP. TI's OMAP4430 SOC is based on ARM Cortex-A9 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
