- Added validation checks in auto_config to reject enabled devices which aren't Q22 capable on Q22 platforms.
- Changed pdp11_cr device to be default disabled in the PDP11 simulator
The logic here is based on the idea that a restore image contains the memory content for a running simulator, while the attached files contain the disk contents for that simulator. If the disk contents have changed since the memory image was created then the two data sets are likely out of sync and disk details cached in memory (i.e. file system information, storage allocation, etc.) will likely result in corrupted disk structures if they are used.
The default behavior is to fail the restore operation if these inconsistencies are noticed. This sanity check can be overridden if the restore command is invoked with the '-F' switch: sim> restore -F simulator-state.file
Also added logging of all erro messages produced during a restore operation to both stdout and a simulator log file if it is being used.
This allows a single simulator executable to be a completely useful component (for those simulators which dynamically load ROM or other boot code).
Meanwhile, we continues to allow the explicit use of a user's preferred ROM or other boot code as well.
A build option is provided in the makefile to not build with the included ROM functionality if desired.
