Using exynos5440 for testing the ACPI interrupt mapping/parsing as this platform uses arm internal timer.

Hi,

As requested by Al Stone and Hanjun I am sending the GTDT asl table. I am not using arndale for testing this as it uses external arm timer coming from exynos combiner which may be complex to use at this stage.

Thanks, Amit Daniel

My apologies for not responding sooner; I have been preoccupied getting some bugs fixed.

Amit: does this patch work as you expect it to on the 5440? Or do you think it needs another revision? I do not have a 5440 to test with so I can't verify it personally.

Other than that, what is our conclusion on this patch? I have no objection to it myself but I think I would prefer to add in all of the files in platforms/exynos5440-ssdk5440.acpi so that we can build a complete blob. Would that be possible?
