[U-Boot] mpc8343: TSEC1 @ RGMII stopped working

[Andre Schwarz]

Kim,

are you using TOT of mpc83xx or master ?

This is already present in current master.

I'm on ToT of current master.
Tried starting a bisect, but couldn't find a working version ... went 
back until v2009.1 ... very strange.

Checking both PHY's with "mii read" clearly showed both PHYs are up and 
running and are configured the same way (besides adress of course).

Checking RGMII I/F with the scope shows that Rx from both PHYs is 
working fine, but TSEC2_TXD[0:3] are dead, i.e. no output at all.
TSEC2_GTX_CLK is active (125MHz) as soon as a Tx should happen.

Will double check the settings.

Felix - is there any chance that you can check your Tx lines of the 2nd 
MAC ?

André
