[E3-hacking] [PATCH v3 2/5(7)] OMAP1: Amstrad Delta: add a handler for processing interrupts generated by the FIQ routine

* Janusz Krzysztofik <jkrzyszt at tis.icnet.pl> [100414 19:24]:
> 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 an
> interrupt source as passed from the FIQ handler.
> 
> It can be registered by the board as a handler for the otherwise unused 32k
> timer interrupt.
> 
> Created and tested against linux-2.6.34-rc4.
> Applies on top of PATCH v3 1/5(7), "OMAP1: Amstrad Delta: add FIQ handler for 
> serial keyboard port interrupt processing".

> v2 changes:
> - add fiq_buffer[] declaration missing from the header file,
> - refresh against 2.6.34-rc2.
> v3 changes:
> - follow Dmitry's serio cleanup suggestions here as well,
> - follow default OMAP GPIO interrupt processing path more closely,
> - more optimizations and cleanups.

Do you really need a separate option for CONFIG_AMS_DELTA_FIQ?
To me it seems you can just compile it in when CONFIG_MACH_AMS_DELTA
is selected.

Also, please make sure the FIQ only gets initialized for the right
board when multiple boards are compiled in.
