Michele,

Support for mpc8540 is already in linuxppc-2.4 tree.
see ppc.bkbits.net

For uboot, go to sourceforge project. u-boot 1.0.0 supports 85xx processors.
see http://sourceforge.net/projects/u-boot

Actually, the linuxppc-2.4 support is incomplete, there's no TSEC/FEC
driver or other on-chip peripheral drivers in that tree to make it
really useful. You could just use a PCI network card to nfsroot a
filesystem and get started, though.

http://www.metrowerks.com/MW/Develop/Embedded/Linux/BSP.htm has
an 8560ADS BSP for download...it probably has some drivers for
on-chip peripherals included.

BTW, you'll need the following patch to linuxppc-2.4 to fix outbound
PCI mem cycles:

I try to download from ppc.bkbits.net, but I have a proxy problem.
About the metrowerks I'll try to contact.

Thanks

Ooops...gotta correct this before I confuse somebody.  The TSEC/FEC
gianfar driver is in the tree...I missed that changeset. :)

Matt's fix is now part of the linuxppc-2.4 tree.  Thanks matt.

We have got a linux port from Motorola (for 8560ADS board), but I'm not sure if I'm allowed to give it away...
We haven't yet tried to run it on the eval board. Anybody out there who has done this?

Please re-read the GPL. Of course you are allowed to give  the  Linux
kernel sources away. This is free software.

Right. But I would prefer that the kernel sources can be downloaded from motorola directly, to avoid to many versions of the same thing...
