ARM: OMAP5: Add minimal support for OMAP5430 SOC
OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture. It's a dual core SOC with GIC used for interrupt handling and with an integrated L2 cache controller. OMAP5432 is another variant of OMAP5430, with a memory controller supporting DDR3 and SATA. Patch includes: - The machine specific headers and sources updates. - Platform header updates. - Minimum initialisation support for serial. - IO table init Signed-off-by: R Sricharan <r.sricharan@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
