Subject: ppc: Move mpc8220 clocks to arch_global_data
X-Git-Tag: v2013.04-rc1~108
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=1c356135fa1fd2c2f6d775ba1b2f86e4823d8338;p=oweals%2Fu-boot.git

ppc: Move mpc8220 clocks to arch_global_data

Move these fields into arch_global_data and tidy up. The bExtUart field
does not appear to be used, so punt it.
