Message:

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.

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

File:

• c/src/lib/libbsp/sh/gensh2/console/Makefile.in (moved) (moved from c/src/lib/libcpu/sh/sh7032/console/Makefile.in) (3 diffs)
