Subject: powerpc/mpic: Use the MPIC_LARGE_VECTORS flag for FSL MPIC.
X-Git-Tag: upstream/snapshot3+hdmi~7004^2~3^2~14
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5a271fe784e799cfeaeac7792b1c87b837e41cbd;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

powerpc/mpic: Use the MPIC_LARGE_VECTORS flag for FSL MPIC.

We should use the MPIC_LARG_VECTORS flag while intializing the MPIC.
This prevents us from eating in to hardware vector number space (MSIs)
while setting up internal sources.
