From 345b77bacabb84a00c7508471ab560b452910240 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 4 Mar 2014 15:34:35 +0100 Subject: ppc4xx: Remove 4xx NAND booting support As ppc4xx currently only supports the deprecated nand_spl infrastructure and nobody seems to have time / resources to port this over to the newer SPL infrastructure, lets remove NAND booting completely. This should not affect the "normal", non NAND-booting ppc4xx platforms that are currently supported.
