From 9ed3246e19a42392bf0fd676dcbbe3539cc46ec1 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 29 Sep 2014 01:37:59 +0900 Subject: powerpc: ppc4xx: remove board support for bluestone This board has been orphaned for more than 6 months. It is the last board defining CONFIG_APM821XX. The code inside #ifdef CONFIG_APM821XX should be removed too.
