epia-m 1/2 baud rate fix

[Mathieu Deschamps]

Hello LinuxBios fellows,

I know i'am a bit asking for trouble in what i like but if not trying to
someone else will anyway (as i've read).
I'am trying to bring this fix smbenablebus.inc into v2, following
advices and notices of Dave

by build time i got :
/mainboard/via/epia/smbus.inc: Assembler message:
smbus.inc:49:Error: invalid character "_" in mnemonic
smbus.inc:50:Error: invalid character "_" in mnemonic
smbus.inc:51:Error: invalid character "_" in mnemonic
crt0.S:155:Warning: inderect jmp without '*'
make[1]: *** [crt0.o] Error 1
make[1]: *** [fallback-rom] Error 1

It stops in 51 in smbus.inc but there are other mnemonics with this
char...

A out-of-the-bit question : I've noticed that we're building a
fallbackrom, and i found the concept unavoidable and very interesting,
but does/should it needs all the capabilities a normal rom has ? 
(for example half rate would be enough, you know thinking let's try not
to give it too much reasons to break down:-)
Indeed i thought fallback rom was some kind of
in-case-of-emergency-boot-anyway-please.. just enough abilities some we
can repair the normal rom to boot up back from. 
Well it just a something that passed by me...


Have nice week-end.

don't worry. I did not apply the patch Dmitri sent. I just used it as a 
guide to the actual changes I made. All your stuff is still in there. 
Check the CVS and you should see your stuff intact. I really need that 
serial port patch though.

That's the next step. Once you bless this V1 port, I start the V2 port. 
That will become the port of choice for EPIA-M.

I'll need some help with that one ... this is a time-available thing for
me right now, but I'm giving it all the time I can.
