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.

This increases VMALLOC_END to 0x18000000, making room for 256MB RAM with the default 128MB vmalloc region. Note that after this patch there's no longer a hole between vmalloc space and the beginning of IO space on omap2 as the first virtual mapping starts at 0xd8000000. Also fold in a related change from Paul Walmsley <paul@pwsan.com> to change the OMAP2_SRAM addresses accordingly.

According to the 34xx TRM Rev. K section 11.2.4.4.11.1 "Purpose of the DLL/CDL Module," the SDRC delay-locked-loop can be locked at any SDRC clock frequency from 83MHz to 166MHz. CDP code unconditionally unlocked the DLL whenever shifting to a lower SDRC speed, but this seems unnecessary and error-prone, as the DLL is no longer able to compensate for process, voltage, and temperature variations. Instead, only unlock the DLL when the SDRC clock rate would be less than 83MHz. Signed-off-by: NPaul Walmsley <paul@pwsan.com>

Mark the SRAM (aka OCM RAM) as Non-cacheable Normal memory[1]. This is to prevent the ARM from evicting existing cache lines to SDRAM while code is executing from the SRAM. Necessary since one of the primary uses for the SRAM is to hold the code and data for the CORE DPLL M2 divider reprogramming code, which must execute while the SDRC is idled. If the ARM attempts to write cache lines back to the while the SRAM code is running, the ARM will stall[2]. TI deals with this problem in the CDP kernel by marking the SRAM as Strongly-ordered memory. Tero Kristo <tero.kristo@nokia.com> caught a bug in an earlier version of this patch - thanks Tero. ... 1.

Add minimal omap3430 support based on earlier patches from Syed Mohammed Khasim. Also merge in omap34xx SRAM support from Karthik Dasu and use consistent naming for sram init functions. Also do following changes that make 34xx support usable: - Remove unused sram.c functions for 34xx - Rename IRQ_SIR_IRQ to INTCPS_SIR_IRQ and define it locally in entry-macro.S - Update mach-omap2/io.c to support 2420, 2430, and 34xx - Also merge in 34xx GPMC changes to add fields wr_access and wr_data_mux_bus from Adrian Hunter - Remove memory initialization call omap2_init_memory() until until more generic memory initialization patches are posted. It's OK to rely on bootloader initialization until then.
