Your question has nothing to do with embedded linux and is  thus  off
topic on this list.

Please post U-Boot related quuestions  to  the  u-boot-users  mailing
list instead.

Yes, U-Boot can use PCI based network  cards  if  there  is  (1)  PCI
support  for  your  board  and  (2) an U-Boot ethernet driver for the
network card

It's not hard at all. An e1000 driver has been ported to U-Boot.

See the drivers/ directory in the U-Boot source code.
