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: 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.
