[U-Boot-Users] [PATCH] tsec.c patch for receiver reset

[Dan Wilson]

When we upgraded from u-boot 1.1.6 to 1.2.0, we found that ethernet no 
longer worked reliably on our 8541-based platforms, although for some 
reason 8548-based systems seemed to work fine.  The problem was traced 
to a missing assignment in function startup_tsec.  We have tried this 
patch on all of our 8541 and 8548-based boards, and it has resolved the 
problem for us.

Any comments or suggestions are greatly appreciated.
