True, the OF is getting a lot of traction. Btw. setting up the mac address in u-
boot is possible too by setting 'ethaddr' variable in the command line. It's
even propagated into the DT node as local-mac-address iirc. I recall the FECes
do not have mac address written in them indeed.
I'm aware of the ethaddr mechanism, but the complication was that the mac
address is a function of the ATCA chassis address, and slot number, and
this must be determined at boot time by means of an onboard ATCA/BMC
controller requesting the address information over an I2C bus from the
shelf manager.
In order to communicate with the BMC, I had to fake a second serial port
in u-boot, by having the console switch back and forth between the real
console and the uart controlling the BMC controller. Also, there are 6
MAC id's to configure, in accordance with a strict requirement. The
serial communication protocol used the IPMI/PICMG3 encoding, and quite
frankly was a bigger pain than the boot protocol ... but I must say that I
learned a lot in the process ... both about U-Boot, the PPC architecture
and ATCA.
ps: Any thoughts about supporting a (net?) BSD on the Palm platforms??
You did some very nice work in this area prior to your graduation!!!!!
I had some ... uh ... disagreement with Theo. Besides, I now work on Linux/U-
Boot a lot, so that's about it.

Thanks why I suggested NetBSD 8-) .... Thanks again for your comments.
They are, indeed well received.
Cheers,
Rob.
