Simon,

Something in the latest u-boot-dm/master branch breaks PCI or Ethernet 
on Jeton TK1 and TX1. I don't know which patch it is. test/py's ping 
test simply fails due to lack of any Ethernet adapter. I don't see any 
errors during either boot or the network test setup scripts, which 
include "pci enum":

TK1 (built-in RTL8169 PCI Ethernet):
Tegra124 (Jetson TK1) # ping $serverip
No ethernet found.
ping failed; host 192.168.100.1 is not alive

TX1 (add-on RTL8169 PCI Ethernet):

I also retested u-boot/master to make sure there's no test system 
infrastructure issue (that branch passes), and re-ran the failing test 3 
times on TK1 with identical results. Other Tegra boards that I test all 
seem fine, at least as far as passing test/py.

P.S. I'll be away next week and the week after. Tom Warren may be able 
to monitor the test system emails, but I don't think I've set him up 
with access to e.g. retrigger tests etc.; perhaps I should look into that...
