Re: [openrisc] [PATCH] Would you like to have UART0 in a xterm ?

[Richard Prescott <rip@step.polymtl.ca>]

It's done (CVS).  This weekend, there was some (2) 'Test failed' on ATS
but I fix them (some forgotten files).

About txfile and rxfile, I could.  I just didn't do it because I am tired
of all those 'if' in 16450.c.  It is not too hard to change two lines in
sim.cfg.  If it is absolutely needed I will.  For now an error msg will
tell you to change your sim.cfg with an example how to do it.

Regards

Richard
