 Changes since U-Boot 1.1.4:
 ======================================================================
 
+* Fixed PCI indirect config ops to handle multiple PCI controllers
+  We need to adjust the bus number we are trying to access based
+  on which PCI controller its on
+  Patch by Kumar Gala 12 Jan 2006
+
+* Report back PCI bus when doing table based device config
+  Patch by Kumar Gala 11 Jan 2006
+
+* Added support for PCI prefetchable region and BARs
+  If a host controller sets up a region as prefetchable and
+  a device's BAR denotes it as prefetchable, allocate the
+  BAR into the prefetch region.
+
+  If a BAR is prefetchable and no prefetchable region has
+  been setup by the controller we fall back to allocating
+  the BAR into the normally memory region.
+  Patch by Kumar Gala 11 Jan 2006
+
 * Add helper function for generic flat device tree fixups for mpc83xx
   Patch by Kumar Gala, 11 Jan 2006
