From 4a238002e71ec018723229f8669363a5ffb7302e Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Thu, 18 Nov 1999 21:22:58 +0000 Subject: Patch from "John M. Mills" with subsequent cleanup from Ralf Corsepius that adds initial Hitachi SH-2 support to RTEMS. Ralf's comments are: Changes: ------ 1. SH-Port: * Many files renamed. * CONSOLE_DEVNAME and MHZ defines removed from libcpu. * console.c moved to libbsp/sh/shared, build in libbsp/sh//console applying VPATH. * CONSOLE_DEVNAME made BSP-specific, replacement is defined in bsp.h * MHZ define replaced with HZ (extendent resolution) in custom/*.cfg * -DHZ=HZ used in bspstart.c, only * Makefile variable HZ used in bsp-dependent directories only. 2. SH1-Port * clock-driver rewritten to provide better resolution for odd CPU frequencies. This driver is only partially tested on hardware, ie. sightly experimental, but I don't expect severe problems with it. * Polling SCI-driver added. This driver is experimental and completly untested yet. Therefore it is not yet used for the console (/dev/console is still pointing to /dev/null, cf. gensh1/bsp.h). * minor changes to the timer driver * SH1 specific delay()/CPU_delay() now is implemented as a function 3. SH2-Port * Merged * IMO, the code is still in its infancy. Therefore I have interspersed comments (FIXME) it for items which I think John should look after. * sci and console drivers partially rewritten and extended (John, I hope you don't mind). * Copyright notices are not yet adapted --- c/src/lib/libcpu/sh/sh7045/include/sci.h | 85 ++++++++++++++++++++++++++++++++ 1 file changed, 85 insertions(+) create mode 100644 c/src/lib/libcpu/sh/sh7045/include/sci.h (limited to 'c/src/lib/libcpu/sh/sh7045/include/sci.h') diff --git a/c/src/lib/libcpu/sh/sh7045/include/sci.h b/c/src/lib/libcpu/sh/sh7045/include/sci.h new file mode 100644 index 0000000000..c18321899c --- /dev/null +++ b/c/src/lib/libcpu/sh/sh7045/include/sci.h @@ -0,0 +1,85 @@ +/* + * Driver for the sh2 704x on-chip serial devices (sci) + * + * Authors: Ralf Corsepius (corsepiu@faw.uni-ulm.de) and + * Bernd Becker (becker@faw.uni-ulm.de) + * + * COPYRIGHT (c) 1997-1998, FAW Ulm, Germany + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. + * + * + * COPYRIGHT (c) 1998. + * On-Line Applications Research Corporation (OAR). + * Copyright assigned to U.S. Government, 1994. + * + * 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 _sh_sci_h +#define _sh_sci_h + +#ifdef __cplusplus +extern"C" { +#endif + +/* + * Devices are set to 9600 bps, 8 databits, 1 stopbit, no + * parity and asynchronous mode by default. + * + * NOTE: + * The onboard serial devices of the SH do not support hardware + * handshake. + */ + +#define DEVSCI_DRIVER_TABLE_ENTRY \ + { sh_sci_initialize, sh_sci_open, sh_sci_close, sh_sci_read, \ + sh_sci_write, sh_sci_control } + +extern rtems_device_driver sh_sci_initialize( + rtems_device_major_number, + rtems_device_minor_number, + void * +); + +extern rtems_device_driver sh_sci_open( + rtems_device_major_number, + rtems_device_minor_number, + void * +); + +extern rtems_device_driver sh_sci_close( + rtems_device_major_number, + rtems_device_minor_number, + void * +); + +extern rtems_device_driver sh_sci_read( + rtems_device_major_number, + rtems_device_minor_number, + void * +); + +extern rtems_device_driver sh_sci_write( + rtems_device_major_number, + rtems_device_minor_number, + void * +); + +extern rtems_device_driver sh_sci_control( + rtems_device_major_number, + rtems_device_minor_number, + void * +); + +#ifdef __cplusplus +} +#endif + +#endif -- cgit v1.2.3
