Hi Ben,

I now have a working linux on my mpc8540 based board, with support for
the compactflash disk and the i2c rtc.

The network tough, does not work yet. altough the the integrated ethernet
controller (FEC) seems to be recognized.  Could it be a problem with the phy ?
I notice that I do not have an entry for gfar_interrupt in /proc/interrupts
on my ethernet-missing linux, while I have one ont the working arch/ppc linux ?
Do I need to give the phy type in the dts file, and how ?

I would also like to know if it is possible to still get in linux the mac
address known by uboot when using a dts file, and how ?

This chiefly depends on whether you're using an old u-boot that
doesn't know about the device tree, or a new u-boot which itself
supplies a device tree to the kernel.

If the old u-boot, you'll need to write a bootwrapper for your
platform which reads the bd_t and pokes the right mac addresses into
the device tree.

If the new u-boot, u-boot itself should put the address into the
device tree.  If it's not, why it's not is a u-boot question rather
than a device tree question.
