From 143a1dec7e04e0a9712ff93e779aabfb21dfd97c Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Wed, 19 Oct 2005 23:11:21 +1000 Subject: powerpc: Merge machdep.h A few things change for consistency between ppc32 and ppc64: idle functions return void; *_get_boot_time functions return unsigned long (i.e. time_t) rather than filling in a struct rtc_time (since that's useful to the callers and easier for pmac to generate); *_get_rtc_time and *_set_rtc_time functions take a struct rtc_time; irq_canonicalize is gone; nvram_sync returns void.
