Peter Maydell recently ran into time-out problems with the prom-env test on a rather slow ARM board. To tackle this issue, we can speed up the test by running QEMU with "-nodefaults" for the pseries machine, so that SLOF has less devices to scan during boot, and by using the "nvramrc" environment variable instead of "boot-command", since this variable is evaluated earlier in the boot process. And to be really sure that we do not face such time out problems again, let's also increase the time out value from 100s to 120s instead.

* This test is used to check that some Open Firmware based machines (i.e.
|
|
* OpenBIOS or SLOF) 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 the firmware 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.
