Subject: [RFC PATCH 06/10] powerpc/mpic: Invert the meaning of MPIC_PRIMARY
Date: Mon, 31 Oct 2011 17:10:07 -0400	[thread overview]
Message-ID: <1320095411-20667-7-git-send-email-Kyle.D.Moffett@boeing.com> (raw)
In-Reply-To: <1320095411-20667-1-git-send-email-Kyle.D.Moffett@boeing.com>

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.
