From 9043f7e95d104795fcb03a2f762524babcd49da5 Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Wed, 28 Sep 2005 20:24:58 +0900 Subject: [PATCH] Sync c-tx39.c with c-r4k.c. tx39_flush_cache_range() does nothing if !cpu_has_dc_aliases. It should flush d-cache and invalidate i-cache since the TX39(H2) has separate I/D cache.
