INTERFACE LEVEL
     Solaris DDI specific (Solaris DDI). The  ddi_mem_rep_put8(),
     ddi_mem_rep_put16(),                    ddi_mem_rep_put32(),

     ddi_mem_rep_putll(),  and  ddi_mem_rep_putw()  functions are
     obsolete.    The    ddi_rep_put8(9F)    function    replaces
     ddi_mem_rep_put8().  The ddi_rep_put16(9F) function replaces
     ddi_mem_rep_put16(). The ddi_rep_put32(9F) function replaces
     ddi_mem_rep_put32(). The ddi_rep_put64(9F) function replaces
     ddi_mem_rep_put64(). The ddi_rep_put8(9F) function  replaces
     ddi_mem_rep_putb().  The ddi_rep_put32(9F) function replaces
     ddi_mem_rep_putl(). The ddi_rep_put64(9F) function  replaces
     ddi_mem_rep_putll(). The ddi_rep_put16(9F) function replaces
     ddi_mem_rep_putw().

PARAMETERS
     handle       The data  access  handle  returned  from  setup
                  calls, such as  ddi_regs_map_setup(9F).


     host_addr    Base host address.

     dev_addr     Base device address.


     repcount     Number of data accesses to perform.


     flags        Device address flags:

                  DDI_DEV_AUTOINCR       Automatically  increment
                                         the    device   address,
                                         dev_addr,  during   data
                                         accesses.


                  DDI_DEV_NO_AUTOINCR    Do not advance the  dev-
                                         ice  address,  dev_addr,
                                         during data accesses.



DESCRIPTION
     These routines generate multiple writes to memory  space  or
     allocated  DMA memory. repcount data is copied from the host
     address, host_addr, to  the  device  address,  dev_addr,  in
     memory  space. For each input datum, the ddi_mem_rep_put8(),
     ddi_mem_rep_put16(),        ddi_mem_rep_put32(),         and
     ddi_mem_rep_put64() functions write 8 bits, 16 bits, 32 bits
     and 64 bits of data, respectively, to  the  device  address.
     dev_addr and host_addr must be aligned to the datum boundary
     described by the function.


     Each individual datum will automatically  be  translated  to
     maintain  a  consistent view between the host and the device
     based on the encoded information in the data access  handle.
     The  translation  may  involve byte-swapping if the host and
     the device have incompatible endian characteristics.


     When the flags argument is set  to  DDI_DEV_AUTOINCR,  these
     functions  will  treat  the  device  address, dev_addr, as a
     memory buffer location  on the  device  and  increments  its
     address  on  the  next  input datum. However, when the flags
     argument is set  to  DDI_DEV_NO_AUTOINCR,  the  same  device
     address  will  be  used for every datum access. For example,
     this flag may be useful when writing from a data register.

CONTEXT
     These functions can be called from user, kernel,  or  inter-
     rupt context.
