Which port to use?

Hi All,

I would like to port NetBSD to a new board but it seems there are 
several different PowerPC ports and I am not sure which to start with.

The board contains a MPC7400 with a 107 memory controller using address 
map B (CHRP). The bootloader is U-Boot, which I have almost finished 
porting (it boots from Flash, just need to get the network working).

Any suggestions which of the PPC ports I should start with? Any other 
advice?

Thanks
Rich

Which board is it?  Got pointers to spec sheets?  It is theoretically possible
that someone else has already looked at it.

It is a custom board. All it has is the CPU, 107, 64MB RAM, 4MB Flash 
and a serial interface. There are a couple of PCI slots one of which has 
an Intel EEPro 10/100 network card.

see man fwctl(8).  # or fwcontrol(8)

     -R filename
             Receive DV stream and dump it to a file.  Use Ctrl-C to stop the
             receiving.  Some DV cameras seem not to send the stream if a bus
             manager exits.  If you cannot get the stream, try the following
             commands:

                   sysctl hw.ieee1394if.try_bmr=0
                   fwctl -r

             The resulting file contains raw DV data excluding isochronous
             header and CIP header.  It can be handled by libdv in the FreeBSD
             Ports Collection.

Sorry, IIDC 1394-based digital camera is not supported. ;-<

I'd probably start with sandpoint or evbppc (which is where sandpoint is
going as soon as I can get to it).

prep would probably work, too.  I've not used it, myself.  The sandpoint
has a pluggable CPU module, but generally has a 75x or 7xxx CPU with a
107 bridge, so it's a pretty close match to what Richard outlined.

Should I be creating a whole new port, or aim just to make a variation 
on an existing port such as the evbppc?

Thanks

The memory maps of PReP and CHRP differ. The PReP memory map is
hardcoded into src/sys/arch/prep/include/bus.h. Richard wrote that his
system uses a CHRP map. So he can't use port-prep without breaking
support for all other PReP machines. Also: port-prep needs the Residual
Data that only (?) a PReP firmware supplies. 

port-evbppc seems to be the best home for Richards system.
