[PATCH 2/2] irqchip/Layerscape: Add Layerscape MSI controller support

[Lian M.H.]

Hi Leo,

Could you tell me how to get the detailed Layerscape route map.
I am not sure that only Layerscape 1 series use the similar GIC and SCFG to implement MSI.
I am even not sure if ls1043 belongs Layerscape 1 series. 

Could anyone tell me how to get the MSI route map?

Thanks,
Minghuan
