   How / when does "ppc_md.set_rtc_time" get filled
in for Lite5200?

Config for support /dev/rtc enables CONFIG_PPC_RTC
which enable driver/char/rtc.c which mentions CMOS_WRITE
panics the kernel!

I trying to use driver/char/genrtc.c.   I can set date
but not hwclock.

> hwclock --set --date="9/22/96 16:45:05"
gen_set_rtc_irq_bit:exit
gen_rtc_ioctl RTC_SET_TIME 00000060
RTC_SET_TIME: Invalid argument
ioctl() to /dev/rtc to set the time failed.
