From 7fd392c2d0b27e372a1771e0bda877820b30d6e0 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Thu, 20 Apr 2006 12:49:05 +0200 Subject: * Add EPCS Controller bootrom work-around for Nios-II Patch from Scott McNutt 11, Aug 2005 -When booting from an epcs controller, the epcs bootrom may leave the slave select in an asserted state causing soft reset hang. This patch ensures slave select is negated at reset. --- include/nios2-epcs.h | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'include') diff --git a/include/nios2-epcs.h b/include/nios2-epcs.h index 2c9522cfd89..20e0c87c89f 100644 --- a/include/nios2-epcs.h +++ b/include/nios2-epcs.h @@ -38,6 +38,11 @@ typedef struct epcs_devinfo_t { unsigned char prot_mask; /* Protection mask */ }epcs_devinfo_t; +/* Resets the epcs controller -- to prevent (potential) soft-reset + * problems when booting from the epcs controller + */ +extern int epcs_reset (void); + /* Returns the devinfo struct if EPCS device is found; * NULL otherwise. */ -- cgit v1.3.1
