I would suggest 2.6.10 if you want an official kernel release.  Is this=20=

board generally available to people?  If so, and you want support for=20
this board in the official kernel, send me your patches for review. =20
I'll then push them up stream.

Be aware there are some infrastrucal changes I'm working on that moves=20=

the 85xx sub-arch support from using OCP to platform_device.  However,=20=

these have minor changes on the board files.

I would take a look at how 2.6 is structured for 85xx.  I tried to do a=20=

better job and provide more common code for a board port to leverage. =20=

So for something like PCI, you should hopefully just have to setup your=20=

memory map and IRQ routing.

I'm not aware of anyone else with another MPC8540 port, I know of other=20=

MPC8560's, and MPC8555/41 ports.
