What about the IBM 2*750FX + MV64360 dev board ?, would this be a port
of Spruce + a different PCI bridge, I cannot seem to find an exact match
in the platforms but there again maybe I am looking in the wrong
tree/directory, thanks.

That's an Argan board and, as you note, its very different from a spruce
so it will get its own port.  That port is being worked on but isn't
ready yet.  If you can hold tight for a bit I will try to get you an
early version.

Okay, here is the problem.  We have a port that works (using 1 processor
only) but its based on the 64360 code that was put into the -galileo
tree.  AFAIK, that 64360 code it not acceptable for the _2_4_devel or
the -2.4 tree so we can't put it in those trees.  There is also a file
with a non-GPL license so that has to be rewritten before anything is
released.

When that's done, I am told there will be a preview kit for it available
from mvista.com.  Preview kits are freely available but you have to
register (free).  Right now, that preview kit is expected to be
available in ~4 weeks but no guarantees.

That's the best I can do so if that's not good enough, you'll have to do
it yourself or maybe someone else has a working src tree they are
willing to share.

Porting Linux into IBM Spruce

[Deepu Paulose Thachil]

Hi,

I am trying to port linux into the IBM spruce board
(PPC750, CPC700..). The board currently works with
VxWorks.. I am using the linux-2.4.20 kernel..

I am not having a linux boot-loader right now. I have
to place the image into the SDRAM using a hardware
debugger tool. The tool that I amusing is Trace32.

There seems to be a problem loading the image into
SDRAm.. I tried to make the variables KERNELBASE and
KERNELLOAD to be 0x00000000.. Is that a correct
approach?? What are the problems that I should take
care of when I make such a change??

I have come to know that there seems to be an "offset"
parameter in the Hardware debugger tool.. Is it of any
use??

Regards,
DP
