* This test is used to check that some OpenBIOS machines can be started
|
||
|
|
* successfully in TCG mode. To do this, we first put some Forth code into
|
||
|
|
* the "boot-command" Open Firmware environment variable. This Forth code
|
||
|
|
* writes a well-known magic value to a known location in memory. Then we
|
||
|
|
* start the guest so that OpenBIOS can boot and finally run the Forth code.
|
||
|
|
* The testing code here then can finally check whether the value has been
|
||
|
|
* successfully written into the guest memory.
