From 0b2a2e5b7747f1f63bd86ca22b5c6097da5b2137 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Thu, 12 Jun 2008 08:05:09 -0500 Subject: [PATCH] cpm_uart: Remove !CONFIG_PPC_CPM_NEW_BINDING code Now that arch/ppc is gone we always define CONFIG_PPC_CPM_NEW_BINDING so we can remove all the code associated with !CONFIG_PPC_CPM_NEW_BINDING.
