From 5d89137a17ca804ee60077f5d4ad8d7ca60f0614 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 10 Apr 2009 20:52:08 +0000 Subject: Blackfin: fix data cache flushing when doing icache flushing Make sure we flush all data caches and their write buffers before flushing icache, otherwise random edge cases could crop up where stale data is read into icache from external memory. As fallout, punt the combined icache + dcache flush function since we cannot safely do them back to back -- the SSYNC is needed between the dcache flush and the icache flush.
