Subject: [U-Boot] [PATCH V3 3/3] ARM: tegra: implement bootcmd_pxe
Date: Tue, 4 Feb 2014 15:59:42 -0700 [thread overview]
Message-ID: <1391554782-7444-3-git-send-email-swarren@wwwdotorg.org> (raw)
In-Reply-To: <1391554782-7444-1-git-send-email-swarren@wwwdotorg.org>
From: Stephen Warren <swarren@nvidia.com>
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>

v3: No change.
