+Module Name:
+
+ vrcpiwrp.c
+
+Abstract:
+
+ This module implements the wrapper for the P1275 boot firmware client
+ program interface. There is a wrapper routine for each of the client
+ interface service. The wrapper routine constructs a client interface
+ argument array as illustraed in the figure below, places its address
+ in r3 and transfers control to the client interface handler. The
+ return address of the wrapper routine is placed in lr register.
+
+ The Client interface handler performs the service specified in the
+ argument array and return to wrapper routine which in turn return
+ to the client program. The client interface handler places the return
+ value (success or failure) in %r3.
+
+
+ Layout of the argument array
