* This include file has defines to represent the overhead associated

* Timing Test Suite to ignore the overhead required to pass arguments
* to directives. On some CPUs and/or target boards, this overhead
* is significant and makes it difficult to distinguish internal
* RTEMS execution time from that used to call the directive.
* This file should be updated after running the C overhead timing
* test. Once this update has been performed, the RTEMS Time Test
* Suite should be rebuilt to account for these overhead times in the
* timing results.
*
* NOTE: If these are all zero, then the times reported include all
* all calling overhead including passing of arguments.

* These are the figures tmoverhd.exe reported with egcs-980205 -O3

BOARD: n/a
BUS: n/a
CPU FAMILY: Hitachi SH
CPU: SH 7032
COPROCESSORS: none
MODE: n/a
 
DEBUG MONITOR: gdb
 
PERIPHERALS
===========
TIMERS: on-chip
RESOLUTION: cf. Hitachi SH 703X Hardware Manual (Phi/4)
SERIAL PORTS: on-chip (with 2 ports)
REAL-TIME CLOCK: none
DMA: not used
VIDEO: none
SCSI: none
NETWORKING: none
 
DRIVER INFORMATION
==================
CLOCK DRIVER: on-chip timer
IOSUPP DRIVER: default
SHMSUPP: default
TIMER DRIVER: on-chip timer
TTY DRIVER: /dev/null (stub)
 
STDIO
=====
PORT: /dev/null (stub)
ELECTRICAL: n/a
BAUD: n/a
BITS PER CHARACTER: n/a
PARITY: n/a
STOP BITS: n/a
 
NOTES
=====
 
(1) The stub console driver (null) is enabled by default.
 
(2) The driver for the on-chip serial devices (sci) is still in its infancy
and not fully tested. It may even be non-functional and therefore is
disabled by default. Please let us know any problems you encounter with
it.

* This include file has defines to represent the overhead associated
* with calling a particular directive from C. These are used in the
* Timing Test Suite to ignore the overhead required to pass arguments
* to directives. On some CPUs and/or target boards, this overhead
* is significant and makes it difficult to distinguish internal
* RTEMS execution time from that used to call the directive.
* This file should be updated after running the C overhead timing
* test. Once this update has been performed, the RTEMS Time Test
* Suite should be rebuilt to account for these overhead times in the
* timing results.
*
* NOTE: If these are all zero, then the times reported include all
* all calling overhead including passing of arguments.
*
*
* These are the figures tmoverhd.exe reported with gcc-2.95.1 -O4
* on a Hitachi SH7045F Evaluation Board with SH7045F at 29 MHz
*
* These results are assumed to be applicable to most SH7045/29MHz boards

NOTES
=====
 
(1) Only stub console driver available at the moment.
Driver for the on-chip serial devices (sci) will be available soon.
 
(2) The present 'hw_init.c' file provides 'early_hw_init'(void) which
is normally called from 'start.S' to provide such minimal HW setup
as is conveniently written in 'C' and can make use of global
symbols for 7045F processor elements. It also provides
'void bsp_hw_init (void)' normally called from 'bspstart.c', shortly
before RTEMS itself is started.
 
These are both minimal functions intended to support the RTEMS test
suites.

* /dev/console for Hitachi SH 703X

* This approach is similar to installing a sym-link from one device to
