[U-Boot] Any experience with BCM5703 - tg3 in u-boot ?

Hi,

I am working on a port of an older tg3 driver to the current U-boot Net infrastructure and I have made some progress in the getting the device recognized on a p4080 - PPC .

The first activity that is attempted to the 570x is a device reset command .. and it fails to respond afterwards.

Any help would appreciated.
