U-Boot, tftp and PCI ethernet

U-Boot, tftp and PCI ethernet

[Brian Padalino]

Does U-Boot support booting over ethernet controllers found on the PCI bus,
specifically I am wondering how hard it would be to boot from an Intel e1000
ethernet controller rather than the on-chip ethernet on my Ebony board.

Has anyone had experience with this, or can point me in the right direction
on where to look to write some simple drivers to support transfers from the
e1000 card, that would be great.

Thanks,
Brian

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.
