-gerrit commit 213eb80a8a071403ca9448dc08b8e00b95f31e67 Author: Dave Frodin <[email protected]> Date: Thu Feb 2 14:56:23 2012 -0700 Force SB800 bootblock to use I/O for PCI config If PCI config cycles use MMIO instead of I/O in the bootblock code the cycles will go nowhere since the MMIO feature hasn't been configured yet. This change forces the cycles to use I/O.
