From 13f5433f700d4da9f6fdf2a4bb80310133a7c170 Mon Sep 17 00:00:00 2001 From: Jon Loeliger Date: Mon, 18 Feb 2008 14:01:56 -0600 Subject: 86xx: Convert sbc8641d to use libfdt. This is the proper fix for a missing closing brace in the function ft_cpu_setup() noticed by joe.hamman embeddedspecialties.com. The ft_cpu_setup() function in mpc8641hpcn.c should have been removed earlier as it was under the obsolete CONFIG_OF_FLAT_TREE, but was missed. Only, the sbc8641d was nominally still using it. It all got ripped out, and the funcality that was in ft_board_setup() was refactored to remove the CPU portions into the new file cpu/mpc86xx/fdt.c instead. Make sbc8641d use this now.
