TAsk #8913: Updated version of poweruphba.sh

MAC/Tools/Power/poweruphba.sh

 #!/bin/bash
 #
-# V3.1, M.J.Norden, 17-11-2015
-# usage: ./poweruphba.sh 5  (or 6 or 7)
-# Power up of the HBA Tiles needs to be slowed down because of high rush-in current. 
+# V4.0, A.P. Schoenmakers, 07-01-2016
+
+# usage: poweruphba.sh RCUMODE (5, 6 or 7) or
+#        poweruphba.sh [-a] -m RCUMODE (5, 6, or 7)
+#
+# Power up of the HBA Tiles. 
 # for rcumode 6 you need to switch the clock seperately (rspctl --clock=160)
 # from MAC version V2_12 and higher you can directly switch between rcumodes
 # The setting of hbadelays with 253 is needed for the new HBA-FE that are default off
 #
 # - automatic clock switch when needed
-# - automatic disble broken tiles from PVSS database
+# - optionally automatic disble broken tiles from PVSS database
