From 5d14a18d59b661356409e5a1f624236155a209ba Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Thu, 20 Oct 2005 22:33:06 +1000 Subject: powerpc: Fix some bugs in the new merged time code I had the sense of the test for when to use the old 601-style RTC registers inverted. pmac_calibrate_decr and via_calibrate_decr weren't setting ppc_tb_freq, on which all the further calculations depended. Lastly, update_gtod was losing the top 32 bits of the new tb_to_xs value.
