From 1a73f0478a289ee5bb2e4f44a6ecf1d6d6410eab Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Sat, 27 Feb 2010 12:53:36 +0100 Subject: [PATCH] MIPS: Alchemy: Remove time_lock. The sole user is au1xxx_calc_clock() which is only used in early bootup where the is no paralellism thus no race condition to protect against.
