Ralf Corsepius <corsepiu@faw.uni-ulm.de> 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
