some issue of sandpoint and powerpc

Hi,
   I am porting sandpoint to my MPC8245 board. 
   I found some issue in the sandpoint port:
     1. sandpoint\machdep.c 
          (1) initppc function:
                memset(&edata, 0, (u_int) &end - (u_int) &edata); 
                this call cause the cpu_info clear to zero, 
                but it init in locore.S:_start
                   INIT_CPUINFO(4,1,9,0)
                so the bss section clear should do in locore.S 
                before INIT_CPUINFO(4,1,9,0) as follow :

          	/* Make sure that .bss is zeroed. */
	li	0,0
	lis	8,edata <at> ha
	addi	8,8,edata <at> l
	lis	9,end <at> ha
	addi	9,9,end <at> l
5:	cmpw	0,8,9			/* edata & end are >= word aligned */
	bge	6f
	stw	0,0(8)
	addi	8,8,4
	b	5b
6:

            or in initppc as follow:
                memset(&edata, 0, (u_int) &cpu_info[0] - (u_int) &edata); 
                cpu_info_end = &cpu_info[0]+1;
                memset(cpu_info_end, 0, (u_int) end - (u_int)cpu_info_end);

That is good! I'm very interesting is NetBSD 3.0 works well on this
beast or there are some troubles floating around. Could you post dmesg
and small notes about your experience with NWS here?

I'm also wish to help you, but unfortunately my NWS knowledge is very
limited, so please feel free ask any support on this mailing list,
port-powerpc <at> .

And thank you very much for your reply.

Good luck!

Re: IBM Network Station (ibmnws) users

Has anyone tried this recently. I would like to know what the current
state of the port is. The last time I tried it, it was serial console
only. Does anyone have first hand experience that says otherwise?
Thanks
Bob

Freescale 7448 eval board

Hello,
   I have a Freescale 7448 eval board 
(http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MCEVALHPC2-7448&srch=1) 
on loan for about a month.

   If anyone is interested in providing some pointers or help I would like 
to try to get NetBSD running on this board.  My actual job is to evaluate 
the 7448 for a low power job; however, since I have the board I would like 
to be able to run NetBSD on it.

What firmware does it have?  It looks like the northbridge is a Tundra.
I don't think we have support for that.

Re: Freescale 7448 eval board

The poweron message indicates U-Boot 1.1.2(Taiga_V2_r2) from Sep 8 2005

My understanding is that Freescale takes the current U-Boot and internally 
(not available to people outside Freescale) modifies it to work on new 
boards with the intention of eventually making the new code public.

If it's not already in public sources, it's available for download from 
the
web site.  Freescale doesn't ship anything with GPL code without the
source also available. There is also quite a bit of public source
available for various combinations of 744x and Tundra or Marvell
host bridges.

Have fun!
