Patch from "John M. Mills" <jmills@…> with subsequent cleanup from
Ralf Corsepius <corsepiu@…> 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/<BSP>/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.
  1. 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
  1. 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
  • Property mode set to 100644

1/*  coverhd.h

3 *  This include file has defines to represent the overhead associated
4 *  with calling a particular directive from C.  These are used in the
5 *  Timing Test Suite to ignore the overhead required to pass arguments
6 *  to directives.  On some CPUs and/or target boards, this overhead
7 *  is significant and makes it difficult to distinguish internal
8 *  RTEMS execution time from that used to call the directive.
9 *  This file should be updated after running the C overhead timing
10 *  test.  Once this update has been performed, the RTEMS Time Test
11 *  Suite should be rebuilt to account for these overhead times in the
12 *  timing results.
13 *
14 *  NOTE:  If these are all zero, then the times reported include all
15 *         all calling overhead including passing of arguments.
16 *
17 *
18 * These are the figures tmoverhd.exe reported with gcc-2.95.1 -O4
19 * on a Hitachi SH7045F Evaluation Board with SH7045F at 29 MHz
20 *
21 * These results are assumed to be applicable to most SH7045/29MHz boards
