Subject: ppc: Move clock fields to arch_global_data
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=748cd0591a9fe9eb23f20748bcb23035cd5ff517;p=u-boot.git

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.
