+    [ARM] 3860/1: Versatile PCI config byte accesses
+    
+    The ARM Versatile board PCI config space read routines are broken for byte
+    accesses.  The access uses a byte read, so masking the bottom two bits of the
+    address is wrong.
+    
+    I guess this is a cut/paste error from the the halfword code which uses
+    aligned word access+shift+mask.
