From 748cd0591a9fe9eb23f20748bcb23035cd5ff517 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 13 Dec 2012 20:48:46 +0000 Subject: [PATCH] ppc: Move clock fields to arch_global_data Move vco_out, cpm_clk, scc_clk, brg_clk into arch_global_data and tidy up. Leave pci_clk on its own since this should really depend only on CONFIG_PCI and not any particular chip type.
