This patch converts the cpu specific interrupt setup code for sh7710 from ipr to intc. While at it new vectors are added to match the information provided by the datasheet. Version two simplifies the Kconfig part. Vectors for IRQ4 and IRQ5 are enabled by default. Use plat_irq_setup_pins() if pins IRQ0-3 should be used in IRQ mode. This patch also adds sh7710 specific platform data for the rtc driver. The base address of SCIF1 is adjusted to match the datasheet.

Computers built with Hitachi SuperH processors always

map the ROM starting at address zero. But the processor

does not specify the range that RAM takes.

The physical memory (RAM) start address will be automatically

set to 08000000. Other platforms, such as the Solution Engine

boards typically map RAM at 0C000000.

Tweak this only when porting to a new machine which does not
