From 7ac2fe2da21d292aeaf3af74e5c80de9ce9dab56 Mon Sep 17 00:00:00 2001 From: Ilya Yanok Date: Tue, 18 Sep 2012 00:22:50 +0000 Subject: OMAP: networking support for SPL This patch adds support for networking in SPL. Some devices are capable of loading SPL via network so it makes sense to load the main U-Boot binary via network too. This patch tries to use existing network code as much as possible. Unfortunately, it depends on environment which in turn depends on other code so SPL size is increased significantly. No effort was done to decouple network code and environment so far.
