From 6cfef5b27e49e826125f12637ee0d7210a896044 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 23 Apr 2007 18:47:08 +1000 Subject: [POWERPC] Rename MPIC_BROKEN_U3 to MPIC_U3_HT_IRQS Rename MPIC_BROKEN_U3 to something a little more descriptive. Its effect is to enable support for HT irqs behind the PCI-X/HT bridge on U3/U4 (aka. CPC9x5) parts.
