Hi Angelo,
Thanks for the reminder, but I'm a bit confused, the previous
version(v10) mentioned that the current upstream mbox has only 2
cells.
So I should follow this rule to remove the extra 0 in the first item as
follows:
 +			mboxes = <&gce 20 CMDQ_THR_PRIO_LOWEST>,
 +				 <&gce 21 CMDQ_THR_PRIO_LOWEST>,
 +				 <&gce 22 CMDQ_THR_PRIO_LOWEST>,
 +				 <&gce 23 CMDQ_THR_PRIO_LOWEST>;

Thanks,
Moudy Ho
