Ah, sorry I was too terse.  It means I used it on the ML300 for
debugging the kernel and drivers.  I also used it to load the
kernel into memory so I didn't have to muck with the CompactFlash.
I mainly used its gdbserver interface, but also did use the telnet
interface at times.  The BDI2000 config file I used was very terse.
The System ACE took care of initializing the hardware so by the
time the BDI got control, most things were pretty much taken care of.
Here's the INIT section from my file:
  [INIT]
  ; init core register
  WSPR    954     0x00000000      ;DCWR: Disable data cache write-thru
  WSPR    1018    0x00000000      ;DCCR: Disable data cache
  WSPR    1019    0x00000000      ;ICCR: Disable instruction cache
  WSPR    982     0x00000000      ;EVPR: Exception Vector Table @0x00000000
  ; Setup MMU info
  WM32    0x000000F0  0x00000000  ;invalidate page table base

Hope that was better,
