From 2cd95a25cb0ee8218b271d23d64fb3f719ac5390 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Tue, 27 Oct 2009 16:20:05 +0100 Subject: ppc4xx: Remove board specific linker scripts from most PPC4xx boards All these linker scripts can be removed since the new common ppc4xx linker script should be able to handle all of those boards. Please test and report problems. Thanks.

This is the default behaviour, since most boards only implement PCI host functionality. This weak default can be overridden by a board specific version if needed.
