Ok see

Ok see
+typedef enum {
+ ZOOM2_REVISION_UNKNOWN = 0,
+ ZOOM2_REVISION_ALPHA,
+ ZOOM2_REVISION_BETA,
+ ZOOM2_REVISION_PRODUCTION
+}

I also made a slight change to the beagle.c in patch 3/3 comment here

/*
* Routine: beagle_get_revision
- * Description: Return revision of the BeagleBoard this code is running on.
+ * Description: Return the revision of the BeagleBoard this code is 
running on.
* If it is a revision Ax/Bx board, this function returns 0,
* on a revision C board you will get a 1.
