[U-Boot-Users] Help Needed !!!

[Deepak $ehrawat]

Hi all,

   I am new to U-Boot. I am trying to port U-Boot on to a proprietary board
based on MPC8560. I am facing following problems :

  1)  PHY device is not being configured ( or initialized ) in ether_fcc.c (
cpu/mpc85xx  directory ). Why?  Aren't we suppose to configure PHY device
when FCC is being used as an ethernet device ? ( as is being done in case of
TSEC in driver/tsec.c )

  2) Has anyone configured BCM5464 ( a PHY device ) connected to TSEC ? If
yes, then can you please send to me the related files (e.g driver/tsec.c )



Regards,
DEEPAK SEHRAWAT

Device get only initialized when actually used by U-Boot.

As Wolfgang mentioned, devices are only configured once used.  Is this
what you're seeing?

I'm not aware of any drivers for this PHY being submitted.  If you have
a datasheet with PHY memory map, writing a driver should be fairly
straight-forward.  Broadcom's very protective of their datasheets, but
if your company has an NDA it should be do-able.
