+/* The uniform boot environment information is restricted to 
+ * hardware information.  In particular for a simple enough machine
+ * all of the environment information should be able to reside in
+ * a rom and not need to be moved.  This information is the
+ * information a trivial boot room can pass to linux to let it
+ * run the hardware.  
+ *
+ * Also all of the information should be Position Independent Data.  
+ * That is it should be safe to relocated any of the information
+ * without it's meaning/correctnes changing. The exception is the
+ * uniform_boot_header with it's two pointers arg & env.
+ * 
+ * The addresses in the arg & env pointers must be physical
+ * addresses. A physical address is an address you put in the page
+ * table. 
+ *
+ * The Command line is for user policy.  Things like the default
+ * root device.
