From 5532553209555c0a5a3c11206ff16192dd465160 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Thu, 29 Jun 2000 23:00:48 +0000 Subject: This is the initial addition of the port of RTEMS to the Hitachi H8 family. This port was done by Philip Quaife of Q Solutions and sponsored by Comnet Technologies Ltd. The port was done based on RTEMS 3.5.1 to a Hitach H8300H. The port was updated to RTEMS 4.5 style Makefiles/configure by Joel Sherrill . While doing this Joel added support for the h8300-rtems to binutils, gcc, newlib, and gdb. NOTE: Philip submitted a BSP for a Hitachi evaluation board which is being merged as a separate entity. --- c/src/exec/score/cpu/h8300/rtems/score/h8300.h | 57 ++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 c/src/exec/score/cpu/h8300/rtems/score/h8300.h (limited to 'c/src/exec/score/cpu/h8300/rtems/score/h8300.h') diff --git a/c/src/exec/score/cpu/h8300/rtems/score/h8300.h b/c/src/exec/score/cpu/h8300/rtems/score/h8300.h new file mode 100644 index 0000000000..becaed362f --- /dev/null +++ b/c/src/exec/score/cpu/h8300/rtems/score/h8300.h @@ -0,0 +1,57 @@ +/* h8300.h + * + * This file contains information pertaining to the Hitachi H8/300 + * processor family. + * + * COPYRIGHT (c) 1989-1999. + * On-Line Applications Research Corporation (OAR). + * + * The license and distribution terms for this file may be + * found in the file LICENSE in this distribution or at + * http://www.OARcorp.com/rtems/license.html. + * + * $Id$ + */ + +#ifndef _INCLUDE_H8300_h +#define _INCLUDE_H8300_h + +#ifdef __cplusplus +extern "C" { +#endif + +/* + * This file contains the information required to build + * RTEMS for a particular member of the "h8300" + * family when executing in protected mode.
