Thanks, Kim

p.s. please consider somehow raising the 40KB post limit so that we may post patches such as these to the list for easier review by all.

p.p.s. please advise whether the u-boot patches mailing list is working for you or not, and whether patches should continue to be submitted there.

Hi agin

Did a quick port to my custom board and I am impressed. I didn't have to change
anything outside my own board port files, great work.

a few snags though:

I can't boot my of kernel, it just hangs after Uncompressing Kernel Image ... OK
Any changes w.r.t OF I need to adjust? I use a compiled in dts.

Also, I get this when u-boot start:
Net:   read wrong value : mii_id 3,mii_reg 2, base e0102320
read wrong value : mii_id 3,mii_reg 3, base e0102320
UEC: PHY is Generic MII (ffffffff)
read wrong value : mii_id 3,mii_reg 1, base e0102320
read wrong value : mii_id 3,mii_reg 1, base e0102320
read wrong value : mii_id 3,mii_reg 5, base e0102320
FSL UEC0: Full Duplex
FSL UEC0: Speed 100BT
FSL UEC0: Link is up
read wrong value : mii_id 4,mii_reg 2, base e0103320
read wrong value : mii_id 4,mii_reg 3, base e0103320
UEC: PHY is Generic MII (ffffffff)
read wrong value : mii_id 4,mii_reg 1, base e0103320
read wrong value : mii_id 4,mii_reg 1, base e0103320
read wrong value : mii_id 4,mii_reg 5, base e0103320
FSL UEC1: Full Duplex

FSL UEC1: Link is up
FSL UEC0, FSL UEC1

1) I don't think eth should start until you actually USE it.
2) The above sequnce takes about 10 seconds to complete.
3) Since I don't have a real PHY(MII to MII) I get these 
   annoying printouts (read wrong value ...). Can't you loose
   them somehow? Some sort of pretend PHY that always returns OK?

4) I still need the "version info in text segment" in start.S

Wasn't there a "generic PHY" patch posted some time ago that might fix this?

Indeed. It's a requirement that Ethernet must NOT be  initialized  if
U-Boot  does  not use it (and then only the port(s) that are actually
used by U-Boot).

I'm pretty sure the generic phy was to allow the use of generic real
PHYs instead of having to add a new entry for each one.  Since the PHY
page/register layout is IEEE-specified, this *should* work for any old
10/100 PHY out there.  I think what Joakim is asking for (and I'm in the
same boat) is to have a 'fake' PHY so when we connect the TSEC to a
switch that doesn't implement MDIO, a happy response is returned during
driver initialization.  Correct me if I'm wrong here...

regards,
Ben

You are right, this is what I need too.
