From 048f4bd7607eb714d4831f90dea6fd27eac9e494 Mon Sep 17 00:00:00 2001 From: Sanjeev Premi Date: Sun, 22 Nov 2009 10:10:54 -0800 Subject: omap3: Runtime detection of OMAP35x devices Add runtime check for these OMAP35x variations based on the detected Si features: OMAP3503, OMAP3515, OMAP3525 and OMA3530. Also, delayed the call to pr_info() into actual variant is detected in omap3_cpuinfo() Signed-off-by: Sanjeev Premi Signed-off-by: Tony Lindgren --- arch/arm/plat-omap/include/plat/cpu.h | 41 +++++++++++++++++++++++++++++++++++ 1 file changed, 41 insertions(+) (limited to 'arch/arm/plat-omap/include/plat/cpu.h') diff --git a/arch/arm/plat-omap/include/plat/cpu.h b/arch/arm/plat-omap/include/plat/cpu.h index 431fec45bbbc..a67439327de3 100644 --- a/arch/arm/plat-omap/include/plat/cpu.h +++ b/arch/arm/plat-omap/include/plat/cpu.h @@ -58,6 +58,23 @@ struct omap_chip_id { */ unsigned int omap_rev(void); +/* + * Define CPU revision bits + * + * Verbose meaning of the revision bits may be different for a silicon + * family.
