Nope, that's why I suggested 2.6's <asm-generic/rtc.h> :) > BTW, what exactly should i do in 'chrp_get_rtc_time' and > 'chrp_set_rtc_time' ?

Something that just dawned on me again (sorry) is that I've really really intended to try and kill both prep_time.c and chrp_time.c (since both of those machine subtypes have PC-style RTC chips) and make them use todc_time.c (see arch/ppc/kernel/todc_time.c). I've got patches to do half of this, against 2.6 (which was a trivial forward port of older 2.4-based patches I had, there is nothing 2.6-specific about these patches). You would want to look at: 006-redo_inb_inw_inl_outb_outw_outl.patch 007-make_out_8_and_friends_synchronous.patch 008-todc_warning.patch 009-prep_time_death-GNU.patch from http://stop.crashing.org:16080/~trini/ -- Tom Rini http://gate.crashing.org/~trini/
