From: Wolfgang Denk Date: Sun, 13 Jun 2010 16:38:23 +0000 (+0200) Subject: Get rid of bogus CONFIG_SYS_BUS_HZ and CONFIG_SYS_CONFIG_BUS_CLK definitions X-Git-Tag: v2010.09-rc1~107^2~15 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=ee80fa7b6e96a43d4270700cddc884e00cdd99fd;p=u-boot Get rid of bogus CONFIG_SYS_BUS_HZ and CONFIG_SYS_CONFIG_BUS_CLK definitions CONFIG_SYS_BUS_HZ has not really been used anywhere except to be redined as CONFIG_SYS_BUS_CLK; in addition, the mpc7448hpc2 had the bogus CONFIG_SYS_CONFIG_BUS_CLK setting which duplicated the funtionality. Change all this to use CONFIG_SYS_BUS_CLK consistently.
