From be8bec56dfac0574c4c08a50cd37e09bea941e3f Mon Sep 17 00:00:00 2001 From: Kyle Moffett Date: Fri, 2 Dec 2011 06:28:03 +0000 Subject: powerpc/mpic: Invert the meaning of MPIC_PRIMARY It turns out that there are only 2 in-tree platforms which use MPICs which are not "primary": IBM Cell and PowerMac. To reduce the complexity of the typical board setup code, invert the MPIC_PRIMARY bit into MPIC_SECONDARY.
