+                around limitations in e500v1 and e500v2 external debugger
+                support. This reduces the portions of the boot code where
+                breakpoints and single stepping do not work. The value of this
+                symbol should be set to the TLB1 entry to be used for this
+                purpose. If unsure, do not change.
