878  * EPOW status sharing (OPAL and the host)
879  *
880  * The host will pass on OPAL, a buffer of length OPAL_SYSEPOW_MAX
881  * with individual elements being 16 bits wide to fetch the system
882  * wide EPOW status. Each element in the buffer will contain the
883  * EPOW status in it's bit representation for a particular EPOW sub
884  * class as defined here. So multiple detailed EPOW status bits
885  * specific for any sub class can be represented in a single buffer
886  * element as it's bit representation.
