Subject: [openrisc] [or1ksim #72] Peripherals that are not-so-clear
Hi,This is the follow-on from #71. These peripherals (fb/ps2kbd and ethernet)
where also halting the sim if a reserved register was acessed but there is no
documentation for the ps2kbd and I couldn't find what peripheral fb is
modelling. The ethernet doc doesn't describe this case. (They might blow up if
their unknown registers are acessed, I don't know).
ChangeLog:
* Don't halt the sim when not needed.
nog.
