1124 	 *
1125 	 * Out of these two methods, the one using STANDBY bits is preferred
1126 	 * way to enable/disable individual blocks. This is because STANDBY
1127 	 * registers are part of system controller which allows system power
1128 	 * up/down in a controlled, pop-free manner. Also, as per application
