[U-Boot] [PATCH 1/2] Get rid of bogus CONFIG_SYS_BUS_HZ and CONFIG_SYS_CONFIG_BUS_CLK definitions
Wolfgang Denk
wd at denx.de
Sun Jun 13 20:10:51 CEST 2010
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.
