NAME
       struct nand_hw_control - Control structure for hardware controller (e.g
       ECC generator) shared among independend devices


SYNOPSIS
       struct nand_hw_control {
         spinlock_t lock;
         struct nand_chip * active;
         wait_queue_head_t wq;
       };


MEMBERS
       lock   protection lock

       active the mtd device which holds the controller currently

       wq     wait queue to sleep on if a NAND operation is in  progress  used
              instead  of  the  per  chip  wait  queue when a hw controller is
