 * Add EPCS Controller bootrom work-around for Nios-II
-   Patch from Scott McNutt 11, Aug 2005
+   Patch from Scott McNutt, 11 Aug 2005
    -When booting from an epcs controller, the epcs bootrom may leave the
     slave select in an asserted state causing soft reset hang. This
     patch ensures slave select is negated at reset.
 
 * Fix I/O Macros and mini-app stubs for Nios-II
-  Patch from Scott McNutt 11, Aug 2005
+  Patch from Scott McNutt, 11 Aug 2005
   -Fix asm/io.h macros
   -Eliminate use of CACHE_BYPASS in cpu code
   -Eliminate assembler warnings
