SYNOPSIS
     rreeggggiieessee [-dd ddeevv] [-DD ttyyppee] [-ii iinnddeexx] [-rr] [-ww vvaall] [-ss nn] [-SS vvaall] [-cc
               nn] [-CC] [-ll] [-xx] [-bb bb::ee] [-vv] [-hh]

UUSSAAGGEE
     To read a register:

              rreeggggiieessee -r [-d devclass] [-D devname] [-i index] [-v] -n reg-
              istername

              rreeggggiieessee -r [-d devclass] [-D devname] [-i index] [-v] -a reg-
              isteraddr -B regsize

     To write a register:

              rreeggggiieessee -w value [-d devclass] [-D devname] [-i index] [-v] -n
              registername

              rreeggggiieessee -w value [-d devclass] [-D devname] [-i index] [-v] -a
              registeraddr -B regsize

     To set a bit or range of bits:

              rreeggggiieessee -s bitindex [-d devclass] [-D devname] [-i index]
              [-v] -n registername

              rreeggggiieessee -s bitindex [-d devclass] [-D devname] [-i index]
              [-v] -a registeraddr -B regsize

              rreeggggiieessee -S value -b b:e [-d devclass] [-D devname] [-i index]
              [-v] -n registername

              rreeggggiieessee -S value -b b:e [-d devclass] [-D devname] [-i index]
              [-v] -a registeraddr -B regsize

     To clear a bit or range of bits:

              rreeggggiieessee -c bitindex [-d devclass] [-D devname] [-i index]
              [-v] -n registername

              rreeggggiieessee -c bitindex [-d devclass] [-D devname] [-i index]
              [-v] -a registeraddr -B regsize

              rreeggggiieessee -C -b b:e [-d devclass] [-D devname] [-i index] [-v]
              -n registername

              rreeggggiieessee -C -b b:e [-d devclass] [-D devname] [-i index] [-v]
              -a registeraddr -B regsize

     To get a list of available registers:

              rreeggggiieessee -l [-d devclass] [-D devname]

     User supplied values are interpreted as follows:

                   Hexadecimal (base-16) if prefixed by '0x' or '0X'

                   Octal (base-8)        if prefixed by '0o' or '0O'

                   Binary (base-2)       if prefixed by '0b' or '0B'

                   Decimal (base-10)     if no prefix

DESCRIPTION
     rreeggggiieessee is used to read and modify hardware registers and physical mem-
     ory.

     -dd ddeevv   specify target device by class

              c cpu (DEFAULT)

              p pci device

     -DD ttyyppee  specify target device by name

              CPU: 750, 750FXDDR1, 750FXDDR2, 7400, 7410, 7450, 7455, 7447A,
                       7457, 970

              Memory: PhysAddr

              Expansion: PCI

     -ii iinnddeexx

              a target all devices (e.g. CPUn)

              n target only device at index n (e.g. -i 0 = CPU0)

     -rr       read register

     -ww vvaall   write val to register

     -ss nn     set register bit n

     -SS vvaall   set register bit range to val (specify bit range with -b option)

     -cc nn     clear register bit n

     -CC       clear register bit range (specify bit range with -b option)

     -ll       list registers and exit

     -xx       list expansion devices (PCI) and exit

     -bb bbeeggiinn::eenndd
              specify bit index range from begin to end for -S and -C actions

     -vv       verbose mode (prints bit definitions)

     -hh       print usage information and exit
