Snapshot problem - comparing SH-1 and SH-2 verions

["John M. Mills" <jmills@tga.com>]

Hello -

"A funny thing happened on the way to ..." rtems-19991203 for the "gensh2"
BSP (Hitachi SH-2, aka 'sh7045'): the polled-console driver from my
patched 4.0.0 version (now 'c/src/lib/libcpu/sh/sh7045/sci/sci.c') now
crashes me at 'fopen()', and doesn't work.

I see a lot of work was done on the 'sh7032' and many of the same changes
were applied [by elfves] to improve the 'sh7045' driver; I would like to
know from anyone using the 'sh7032'/"gensh1" code, whether that console
('/dev/sci1') is working. If so, I will pull the 'sh7045' driver into line
with the 'sh7032' version. I would also be happy to hear from other
'sh7045' users, so I can trouble someone other than Ralf C. with my
incessant questions. (Even Ralf's and Joel's patience must have limits
&;^).

I am targeting the Hitachi SH7045F EVB for "gensh2". My development host
is GNU/Linux-2.2.5 (RH6.0). I have had some trouble building the toolset
and am currently using: 'gcc-2.95.1-binutils-2.9.1-newlib-1.8.1' (the
first and last being somewhat "hand built"). I am debugging under WinNT
with Hitachi's HDI-4 and the corresponding monitor for this EVB. (Not
great, but worked without any changes so I've stayed with it.)
