removal of arch/ppc in 2.6.27?

removal of arch/ppc in 2.6.27?

[Kumar Gala]

This is intended as a reminder that we plan on getting rid of arch/ppc  
this summer.  I'm guessing based on kernel release times that will be  
2.6.27.  That would mean 2.6.26 will be the last kernel to support  
arch/ppc.

If people have boards that like ported over please let us know and  
work with us to port this over to arch/powerpc.

Here is a list based on arch/ppc/platforms.  Its not intended to be  
complete but a general idea of what's left in arch/ppc.

This is in arch/powerpc

These are also supported in arch/powerpc; we just don't have .dts
files for the reference designs merged yet.

I have one of these.  I'll port it eventually.

It would be nice to see the mbx860 get forward-ported.  I just have not
had any time to get to it.

I would very much like to see mvme5100 move to powerpc.

I'll help any way I can including trying to port it myself.

Is it significant that in arch/powerpc/platforms/prep/Kconfig
PPC_PREP depends on BROKEN ?
What are the implications of that?

Thanks,

Dwayne

will this be the end of life for all the PReP's ? I remember a patch posted 
some month ago, but didn't heard anything since then. Any news? Or just let 
it die quietly?

No, I'm still planning on getting PReP support over to arch/powerpc,
but getting time to work on it has been the difficulty.

What sort of PReP do you have?

On my side, I have MVME2[467]xx boards. But these are actually PPLUS
board but the residual data and boot methods are so similar to PreP
that they could be merged. The host bridge is flexible (the MVME5100
has the same PHB but a completely different layout set up by the
firmware IIRC). I have local patches in the tree I use (still 2.2)
that make the memory map more CHRP like (to have more PCI memory
space and less I/O space).

The main problem is that I'm short on cycles to work on porting
them to 2.6 (the other is that I'm not sure that it's worth
putting 2.6 on machines with 16MB of RAM, current kernels
with extremely stripped down configs are still much  larger
than the ones I run on these boards).

IBM 7248 (aka Carolina) and Motorola Powerstack II (aka Utah) - currently 
running Debian with 2.6.18 kernel.

I have a 43P-140, which I bought on eBay a few weeks ago to add to the
Fedora testing pile. Foolishly I was trying to get the CHRP kernel
booting on it, just because it says 'chrp' in its device_type.

Unfortunately I seem to have killed it -- I tried to update its firmware
from TIG97251 to TIG04204 and although the update looked successful, it
never came back. Says 'F2A' on the diagnostic panel. I renamed the
firmware file on the floppy to 'precover.img' as the documentation
suggests, but it never even looks at the floppy drive when it starts up.

Anyone know if the firmware flash on these can be removed and flashed
externally, or have any better suggestions?

I am still struggling to make SPRUCE work with 2.6.24 arch/ppc. I think no
body had tested 2.6.x on SPRUCE. I think there is some issue with cpc700 pic
driver.
I feel it is better to move SPRUCE along with other arch/ppc boards to
arch/powerpc

Thanks,
Suresh
