From be95b3d9ea5e9478a52d8fca66b62ed85b39dc08 Mon Sep 17 00:00:00 2001
From: Stephen Warren <swarren@nvidia.com>
Date: Thu, 23 Jan 2014 13:17:04 -0700
Subject: [PATCH 10/13] ARM: tegra: implement bootcmd_pxe
This retrieves a PXE config file over the network, and executes it. This
allows an extlinux config file to be retrieved over the network and
executed, whereas the existing bootcmd_dhcp retrieves a U-Boot script.
Signed-off-by: Stephen Warren <swarren@nvidia.com>
