[U-Boot] OpenRD base/client support?

[U-Boot] OpenRD base/client support?

[Simon Kagstrom]

Hi!

I'm working on a OpenRD base board which is currently shipped with an
old U-boot source archive (1.1.4). I understand that Marvell support
for more boards are in the pipe, so I just wanted to ask if the work on
the OpenRD has started?

It works "pretty well" with U-boot built for sheevaplug - my main
problem now is that it hangs on miiphy_reset.

Thanks,
// Simon

I can confirm that. Have the same behaviour but haven't time to investigate further.
Maybe we can share information and coordinate some work?

Sure. I've created a board support package for OpenRD base which is
still basically a copy of sheevaplug. I can submit it if Prafulla wants
to, but it's very preliminary still.

The problem with the phy_reset was simple though: The phy simply has a
different address than the one for sheevaplug. The patch below (against
my board package - not possible to apply!) fixes this.

Simon,
could you please post it on the list, or if this is uncommon send it per mail to me?

Thanks in advance,
Dieter

I would like to welcome this patch, we can make it complete.
Meanwhile I will try to look details about openRD, any pointers will help me
