12 * This test is used to check that some Open Firmware based machines (i.e.
13 * OpenBIOS or SLOF) can be started successfully in TCG mode. To do this, we
14 * first put some Forth code into the "boot-command" Open Firmware environment
15 * variable. This Forth code writes a well-known magic value to a known location
16 * in memory. Then we start the guest so that the firmware can boot and finally
17 * run the Forth code.
18 * The testing code here then can finally check whether the value has been
19 * successfully written into the guest memory.
