From c87b6ebaea034c0e0ce86127870cf1511a307b64 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Sat, 28 Oct 2006 01:14:37 +0900 Subject: [PATCH] [MIPS] mips hpt cleanup: get rid of mips_hpt_init Currently nobody outside time.c require mips_hpt_init(). Remove it and call c0_hpt_timer_init() directly if R4k counter was used for timer interrupt.
