Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

* OMAP cpu type detection

ARM: OMAP: Add OMAP chip type structure; clean up mach-omap2/id.c Add a new OMAP chip identification interface, omap_chip_id. omap_chip_id is a structure which contains one bit for each OMAP2/3 CPU type, and on 3430, ES level. For example, the CHIP_IS_OMAP2420 bit is set in omap_chip at boot on an OMAP2420. On OMAP3430ES2, both CHIP_IS_OMAP3430 and CHIP_IS_OMAP3430ES2 bits are set. omap_chip is set in mach-omap2/id.c by _set_omap_chip(). Other code should use the omap_chip_is() function to test against omap_chip. Also, clean up id.c by splitting some code out of omap_check_revision() into its own function, _set_system_rev(); and converting some debug printk()s into pr_debug(). Second revision.

omap: Add chip id recognition for OMAP4 ES2.1 and ES2.2 Allow OMAP4 ES2.1 and ES2.2 revisions to be recognized in the omap4_check_revision() function. Mainly, ES2.1 has fixes that allow LPDDR to be used at 100% OPP (400MHz). ES2.2 additionally has a couple of power management fixes (to reduce leakage), an I2C1 SDA line state fix, and a floating point write corruption fix (cortex erratum). Even though the current mainline support doesn't need to distinguish between ES2.X versions, it's still useful to know the correct silicon rev when issues are reported. Moreover, these id checks can be used by power management code that selects suitable OPPs considering the memory speed limitation on ES2.0.

ARM: OMAP4: Add minimal support for omap4 This patch adds the support for OMAP4. The platform and machine specific headers and sources updated for OMAP4430 SDP platform. OMAP4430 is Texas Instrument's SOC based on ARM Cortex-A9 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and SCU for cache coherency.

#define __ASM_ARCH_OMAP_CPU_H
ARM: OMAP: Split plat/cpu.h into local soc.h for mach-omap1 and mach-omap2 We want to remove plat/cpu.h. To do this, let's first split it to private soc.h to mach-omap1 and mach-omap2. We have to keep plat/cpu.h around until the remaining drivers are fixed, so let's include the local soc.h in plat/cpu.h and for drivers still including plat/cpu.h. Once the drivers are fixed not to include plat/cpu.h, we can remove the file. This is needed for the ARM common zImage support.

#ifdef CONFIG_ARCH_OMAP1
ARM: OMAP1: Remove relative includes As discussed on linux-arm-kernel, we want to avoid relative includes for the arch/arm/*omap* code: http://www.spinics.net/lists/linux-omap/msg80520.html Note that eventually when the omap1 specific drivers are fixed to not use cpu_is_omap macros and not depend on mach/hardware.h, this patch can be reverted and these headers can be local. But since just fixing the drivers for omap2+ is already a big enough hassle, let's deal with that properly first.

omap: Fix incorrect 730 vs 850 detection Commit cd92204924fafbd5c7241dfd12ca3176d542e0c5 added support for omap850. However, the patch accidentally removed the wrong ifdef: # define cpu_is_omap730() 1 # endif #endif +#else +# if defined(CONFIG_ARCH_OMAP850) +# undef cpu_is_omap850 +# define cpu_is_omap850() 1 +# endif +#endif ... void omap2_check_revision(void); #endif /* defined(CONFIG_ARCH_OMAP2) || defined(CONFIG_ARCH_OMAP3) */ - -#endif Instead of removing removing the #endif at the end of the file, the #endif before #else should have been removed. But we cannot have multiple #else statements as pointed out by Alistair Buxton <a.j.buxton@gmail.com>. So the fix is to: - remove the non-multi-omap special handling, as we need to detect between omap730 and omap850 anyways. - add the missing #endif back to the end of the file Reported-by: Sanjeev Premi <premi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
