Hello, On my Pegasos/CHRP box, i noticed that not setting the CONFIG_RTC option in the Character device part of the configuration (not to be confused with the CONFIG_GENERIC_RTC and CONFIG_PPC_RTC options in the General setup part) will cause some strange delay when setting the hardware clock on my box, and i believe the clock will be badly set (have to check again to confirm though). Setting CONFIG_RTC will fix that, and furthermore, in the help of the CONFIG_RTC there is some mention of this option being needed for using the RTC clock in a SMP compatible fashion.
So, i believe this option is needed for me, and probably also for the powerpc-smp config. But, since the powerpc configurations are common to many subarch, there is maybe a reason for not having this options set, and i would like to know if setting it per default in the powerpc and powerpc-smp configurations, but not in the powerpc-small one, is likely to break on some of the supported powerps subarches out there. Friendly, Sven Luther
