Trying to find out the current state of Linux on a MPC 8260

Trying to find out the current state of Linux on a MPC 8260

[diekema_jon]

	* I am starting the work of bringing up Linux kernel on the EST
	Corporation, http://www.estc.com/, SBC 8260 product.

	Ultimately, we will have a custom board that contains a MPC
	8240/8260 but the hardware development won't be real for a long
	time.

	I would like to leverage off of the work of others doing the 82XX
	Linux ports.  I have a number of basic questions, that I could use
	some help with:

	1) Where are the CVS archives that capture the PPC kernel
	   development activity located?  Do they support anonymous
	   access?  If not, what do I need to do to gain access as a named
	   user?

	   I have used anonymous CVS access to cvs.on.openprojects.net
	   before, but I am not sure that this is best choice.
	   http://cvs.on.openprojects.net/ doesn't give me any hints.

	   Example:
	
	   setenv CVSROOT ":pserver:anonymous@cvs.on.openprojects.net:/cvs/linux"
	   cvs login
	   cvs -z 3 checkout linux
	   cvs logout

	2) Has anybody gotten Linux kernel to run on the EST Corp. SBC 8260
	   board?  Or, is anybody is the process of doing this?

	3) Has anybody gotten Linux to run on the 8240/8260?  If so,
	   are there some hints or recipes available?

	   Dan Malek reports

	   "I am nearly ready to post the first 8240 and 8260 changes.
	   The 8260 is an extension of the 8xx stuff today.  The 8xx is
	   somewhat changed to accomodate this, and will be in the 2.3.x
	   kernels."

	   Has this been done?  If so, where can I get the source?

	4) What is best way to get in touch with embedded MPC 82xx
	   developers?

Yes.  Yes.

A very fine company has paid me money to port Linux/PPC to the
EST 8260 (not EST).  I have it nearly completed and when they are
satisfied it meets their needs I will update the CVS according to
their wishes.  There is some software associated with it that
was not derived from GPL, althought it would be nice to include
that as GPL in the Linux tree.  The port will include support
for the serial ports, Ethernet on SCCs, and 10/100 on the FCCs.

Motorola gave me an 8240 Sandpoint that I have been using in
my free time to port Linux/PPC.  Since this is a personal
contribution of mine, people that pay me obviously have priority :-).
I should update CVS with the current sources....there are still
some bugs in the configuration of the interrupt controller for
the ISA bridge and 8259.

You just did it.

What CVS archives do you update?  

Is it ":pserver:anonymous@cvs.on.openprojects.net:/cvs/linux"?  

What are the collection names that contains the updates?  Is it just "linux"?

I have access to the vger CVS tree, and only update the minimal
embedded 8xx and 82xx files.  I rely heavily (and thankfully :-)
on others to ensure these changes are propagated into Linus'
and other trees.

Yes, for the kernel.

I think it is time to remind everyone finding, compiling and booting
a kernel is actually the easy part of the development effort.  The
real challenges are the applications.....creating the development
environment with compiler, libraries, debuggers and other tools
is time consuming.  I try to make the embedded things I do work
as closely to a desktop or server as possible, but there are
sometimes differences.
