CONFIG_SYS_CLK_FREQ is the standard way to set the system clock frequency. On MPC83xx, CONFIG_83XX_CLKIN is used for this purpose. Hence, the obvious way is to replace CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ. A few MPC83xx boards use the CONFIG_83XX_CLKIN variable for computing CONFIG_SYS_NS16550_CLK. This makes it harder to replace CONFIG_83XX_CLKIN. But the value of the multiplicator can be read from the SPMR register. Hence, replace the static calculations with a call to a new get_bus_freq function, as other architectures do. Signed-off-by: Mario Six <mario.six@gdsys.cc> |
