The common code just needs the C0_COUNT as free running counter, without the need of writing and checking C0_COMPARE. The function get_tbclk() is still implemented here instead of changing all places of CONFIG_SYS_MIPS_TIMER_FREQ to CONFIG_SYS_TIMER_RATE. The change was tested on a MIPS32 system, but as the MIPS64 code was/is the same, this should be no problem. Signed-off-by: Thomas Langer <thomas.langer@lantiq.com>
