commit 84d0c2f1e39caff58bf765a7ab7c72da23c25ec8
Author: Kim B. Heino <Kim.Heino@bluegiga.com>
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 <at> embeddedspecialties.com.
+ 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.
We already have a vendor subdir for Atmel, so we should use it.
