Janusz Krzysztofik 11f9562a42 OMAP1: Amstrad Delta: add a handler for processing interruptsgenerated by the FIQ routine
This patch introduces an IRQ handler used for processing interrupts generated
by the FIQ handler when it decides there are data ready for processing.

The handler further invokes device specific interrupt routines based on
interrupt source counters passed from the FIQ handler.

The handler setup function is intended to be called from the board
provided init_machine() callback.

Janusz Krzysztofik 60c3bf3f12 OMAP1: Amstrad Delta: add FIQ handler for serial keyboardport interrupt processing
This patch introduces a Fast Interrupt Request (FIQ) handler for Amstrad Delta
(E3) videophone. The handler's purpose is to process interrupts generated by a
GPIO line that a serial keyboard clock hangs off. It collects consecutive bits
into words, pushing them into a buffer, then requests a higher level interrupt
after one or more words are ready for further processing by a keyboard port
driver.

The handler also processes interrupts generated by two other GPIO lines, used
by other on-board supported devices, by simply requesting a higher level
interrupt, that in turn should invoke those device's specific irq handlers.

IRQ12 line, not used by OMAP1510 hardware (described as reserved), has been
choosen as a higher level interrupt source.
