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.

ARM: OMAP2+ Move SoC specific headers to be local to mach-omap2 These can now be moved to be local headers in mach-omap2. Note that this patch removes arch/arm/plat-omap/devices.c as it will get removed anyways with Paul Walmsley's patch "ARM: OMAP: split OMAP1, OMAP2+ RNG device registration".

ARM: OMAP4: ID: Improve features detection and check Replaces several flags bearing the same meaning. There is no need to set flags due to different omap types here, it can be checked in appropriate places as well.

OMAP4_HAS_FEATURE(perf_silicon, PERF_SILICON)
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.

ARM: OMAP2+: Limit omap initcalls to omap only on multiplatform kernels We need to make sure that multiplatform kernels don't run omap initcalls when booted on other SoCs. Do this by adding wrapper macros for the initcalls that return early if soc_is_omap() test fails. This allows us to easily change the defines later if we have SoC specific init sections available.

ARM: OMAP2+: omap_device: use late_initcall_sync If DEBUG_LL and earlyprintk are enabled, and omap-serial.c is compiled as a module, the kernel boot hangs early as the clocks for serial port are cut while earlyprintk still uses the port. The problem is a race between the late_initcall for omap_device (which idles devices that have no drivers) and the late_initcall in kernel/printk.c which turns off the earlyconsole. Any printks that happen between this omap_device late initcall and the earlyconsole late initcall will crash when accessing the UART. The fix is to ensure the omap_device initcall happens after the earlyconsole initcall.
